Because it is only legal to buy or possess full auto that was manufactured and registered before 1986. Because of the small # of guns that fall into the legal category a M16 for example goes for between 5 & 6 grand. The good news is the stamp is only $200.

RAL

That adaptor did not make anything full auto any more than the SlideFire does or the little crank that's popular on the Ruger 10/22. It was still one trigger pull, one shot. It just did it very fast - exactly like the SlideFire. Why it disappeared, I don't know.

He wanted to know why not just go out and get a full auto and I was addressing the realities $$$$$$$$ of that route.
The slidefire is a bit overpriced for what it is IMHO but compared to owning a real full auto....I guess its a bargain?



RAL

I agree with you on that. Something I haven't seen is years was a full-auto .22 LR on the Thompson pattern. It was made by Auto-Ordance (if I remember correctly) in the mid-70s and was aimed at the LE community. A generous supporter of our local Sheriff's department bought three of them for the department. They were a ball to shoot (a few of us non-LE people had friends that let us shoot them) and it was amazing how much damage a .22 could do at 450 rounds/minute to a solid 8" cinder block - a two inch hole all the way through it in about 15 seconds. Unfortunately, the Sheriff was afraid of publicity so they were never actually used for anything but playing at the range. I WOULD LOVE TO HAVE ONE OF THOSE!!!

The American 180? Had a 180 round drum mounted on top. Ya that would be a cool gun to own. If memory serves me correctly they were targeted for prison guard use?


RAL

Yup, that's it. Boy, it was fun to shoot.

Just an interesting note about Connecticut's AWB ...

Full auto is perfectly legal here, but NOT select fire - full auto or nothing.

If memory serves correct, that was the akins or atkins, something like that, accelerator. It did exactly that, accelerate the rate of trigger pull. When you made one rotation of the crank, it pulled the trigger multiple times so it wasn't truly one pull by you. The slidefire is legal because your finger is what's actually hitting the trigger, it's just inertia and your opposing forward force that makes you pull it very rapidly.

Ok, so I shouldn't drink and reply to forums lol. The crank wheel was something completely different.They approved the accelerator because there was a prototype shipped to the batf and it malfunctioned during testing so all they had their decision based on was what they could conclude in theory by inspecting it. After it was approved, one of the employees that was involved in testing thought it was such a great idea that he went out and spent the around a thousand bucks for one. After he used it, he suggested to his supervisor they re-evaluate it. Upon re-evaluating a functional product, they determined it not to be legal. They used a bunch of loopholes here and there but what they finally decided was it was the two springs in the stock that aided in it being a machinegun. So they actually outlawed the springs from the stocks, that's why they only confiscated officially the springs from Bill Akins. They just told everyone else on his customer list that they had to turn over the entire stock, so they did. Last I heard Bill Akins was trying to bring the Accelerator back to market legally though. I'd have to look more into it that one

And for the record, the crank thing is called the BMF Activator. I think it's solely for the 10/22's tho. You can find them on gunbroker for like 20 bucks.

It doesn't matter if one rotation pulled the trigger 100 times - it was (and is) still just one round fired for each pull of the trigger.

Just like the SlideFire - neither gives you full auto.

You can put one on any semi-auto. There was a guy at the range this morning that had one on a 9mm carbine.

Oh perfect, even better! Thanks for the help

I had a crowd watching me shoot my Slide Fire modded 15-22 yesterday. Had a Black Dog drum attached. Shooting CCI Mini Mags is a dream. 600 rnds in no time

This is where all the 22 ammo is disappearing to! 😮

A buddy of mine has a model 1928 Thompson sub machine gun. Its worth about $20,000.00. After shooting that, a bump fire/ slide fire .22
just wouldnt cut it. Half the fun of full auto is just trying to control the gun, and the thrill comes from feeling that recoil push you back, and seeing the flame shoot out of the barrel and cutts compensator. There is no way a 22 could even compare, so I have no desire to get one for my 15-22. Now if you never shot full auto I could see wanting something like this, but it really is a poor substitute. Shot a BAR and an MP-40 couple of times too at a show. had to pass on the flame thrower..cost too much to shoot

One with the Plinker tactical Magazine..........Building the Perfect Bump-Fire .22 with Plinker Tactical and Slide Fire - YouTube

You don't have to put it on the 15-22, it's just cheaper. I agree with the fun being trying to control it and all the gas blowing back in your face.

I've found that using the mini mags with the slide fire is a dream also. Federal 40 work well also. fed 36 not so good. Can't wait to get my drum and find some more mini mags.

Nor sure I agree. I've shot a $20K MP5 and my Slide Fire MP15-22 is just as fun and a heck of a lot cheaper.

just finishing up a build on the 15-22 with a slide fire, installed the CMC trigger and purchased a "reverse" muzzle brake from weaton arms.took a few try"s to get it to function, theres a little technique to get her going..lots of fun, but the down side is ive got around $1100 in this thing, ( cost of the rifle,trigger,slide fire, brake),,,,,and with 22 ammo going thru the roof,dont know if i did the right thing or not. take a look on u-tube, look for weaton arms vidieo on the hole process of the build.

Tuff times for sure Now....

im even concerned that my 7k rds will last me long enough.....

You shouldnt really need the revearse muzzle brake if youve got the right trigger and technique. My 15-22 has no threaded barrel and thats the model I was told worked best with slide fires because of less weight without the brake. I used a Rock River 2 stage trigger off another AR I had and it works fine. Initally it would only do 3 to 5 round bursts until I began gripping it in the magwell area. I added a FAB defense magwell grip to remind me where to grip it, and push forward with my thumb on the rail. It seems to have got easier because now I can do full mag dumps regardless of where I grip it and thats with a red dot, magnifier, Arms folding front sight, Troy battlesight rear folder, Daniel Defense rail sling mount, magpul ladder rail covers, and the threaded barrel adaptor with an A2 flash hider and crush washer. Maybe my techniques improved or some kind of "break in" has occured but it seems to run fine with just about any ammo. I dont do drum mags but two of the plinker tactical 35 round mags taped together dont seem to stall it either and fully loaded thats alot of wieght.

It really is all technique. You do need a lighter trigger, but other than that "it's all in the wrists" lol.

Wow! That is a lot of weight. Impressive that you can regularly mag dump with that setup.

Anything below 1100 fps will not run in my setup. I have a 15-22 that was actually modded by SlideFire themselves.

CCI standard velocity and Aquila SSS 60Gr or Wolf .22lr are a no go. Nada..not even a two round burst.

CCI 36gr 1285fps mini mags flow like silk Federal 36Gr also run well. Golden Bullets will also fly out of the barrel until they inevitably glitch.

I have stocked CCI mini mags and now run them almost exclusively.

My technique is decent but could use a little work. I have a front grip which I have learned to merely tug forward rather than actually grip.

I recently bought a M&P 15-22 with a slide fire stock installed from the factory.

It is product code 811033 and has a sticker on the outside of the
box " SFS Firearms SBS RH BLK "

It works well right out of the box and seems to be even more
effective with my Coastal Hornet 22 rimfire suppressor mounted
on the threaded barrel.
It of course ,likes high velocity ammunition.

For those keeping track the serial prefix is 'DZY' and the julian date
is '2311 ' which would put production about October 2012.

Good luck,

Allen Frame

Allen,

This was installed by SlideFire not S&W. It should also have their 3.5# trigger and the reverse muzzle break. S&W never sold a factory installed Slide Fire model (AFAIK).

Did it come with a muzzle break that you removed for the suppressor?

Tom

I'm about 90% sure SlideFire sold that as a product at one time but it has been pulled now. I remember seeing it a while back but it doesn't appear to be on their site any longer.

For now. I bet these are on the legislative skyline.

Slidefire did sell an entire 15-22 a while back, but seem to have dropped it from the website. Weight, Technique, and placement seem to be just as important as trigger. If I move the red dot out on the rail where I like it on a typical AR, it stalls. Mine also does not seem to like Federal bulk in bumpfire mode. Orgone 1, I usually go to shooters on the weekends. Ive heard of your crowd drawing skills from Star. Maybe ill run into you there and we can compare notes.

Technique is the key....

Once I STOPPED using the Slidefire on my AR15.. My Skills returned again... was thinking it was the Gun... but once i stopped with the Ar15 BumpFire I got the 15-22 to mag dump every time

Now Mine LOVES the Federal Bulk Ammo.. dont shoot Much CCI.. to spendy for that... The Blazer werks OK... the Federal seems Much better for me...

S&W M&P 15-22 with Slide Fire Stock Shooting - YouTube

Sure does look like fun to shoot!

I seem to have best luck with 40gr bullets. Not many 36gr work for me. I'm going to do a little polishing work and see if it helps at all. Federal bulk hasn't worked well for me, but same rings true without the SF. Weight hasn't seemed to be an issue, for me at least. I've had my Strikefire, burris bipod mount that I have my sling attached to that's made of billet aluminum, grippod, factory sights, and the thick ladder rails that stick out a bit, and a laser. We'll see with the 50-rd drum full, but I don't see it as a problem. For me it works best by holding the stock real tight into my shoulder, thus holding most of the weight of the rifle that way. Than my left hand(I'm a right handed shooter) I barely grasp my grippod(or magwell, some have better luck learning that way) and instead of using my left hand to push forward, use mostly just my thumb. When teaching people I actually just have them stick their thumb out like they're hitchhiking and put it behind the grip and just push lightly forward with just their thumb, not entire hand. With a 3lb trigger and friction coefficient I'd estimate it's only taking around 5lbs of forward pressure. The issue I see the most is pushing forward too hard, thus not letting the recoil reset the trigger. I used a silicon spray on the buffer tube and block and it's smooth as silk. It even works with my "frankenblock" I made for the SF, although I now have that block on the Sport and factory one on the 15-22. Your support hand has to let the rifle move freely as it's not moving very far. Once you get it down, it's great. And you actually can control rate of fire when you learn where the reset point in your trigger is. By letting it travel further back past the reset, it takes more time and slows your cycle rate, or just barely letting it reset will speed it up. That's pretty advanced technique, but with practice it is do-able. This is the fastest cycling I've been able to achieve, and slowing it down adds about 3/4 of a second to a full 25rd dump.

Here's one that shows the cycling a little slower, just to get an idea of what I'm talking about. It speeds up a bit at the end, but if you watch it a couple times you can hear the difference.
http://www.youtube.com/watch?v=IiAfjHFK0aM&sns=em

Edit:found a video that was even slower. I pushed too hard forward at the beginning, you can see where it was a 2rd burst, than dump.

That would be fun!

There is a company out there called Wheaton arms that offers a reverse muzzle break to give the mp15-22 a little more recoil for the slide fire to work. Have to install the CMC trigger kit that they offer also.

SlideFire also made a special reverse muzzle break for their modded 15-22. I need to take a pic and upload it. It is pretty nifty looking with tiny holes circling the barrel. Not clear to me how much of a difference it makes but the folks at Slidefire thought enough of it to special manufacture the item for their unit.

Just wanted to do some updates on my Slidefire

So have a Timney trigger... love it think its a great Trigger. kept reading about the CMC and how well it does.... so i got one to try

1st off i dropped it in my S&W Sport.... WOW..... thing HITS like a donky... the Hammer spring is WAY stronger than the timney and STock Trigger... i mean Way Stronger...
Timney was just at 3lb3oz
CMC was at 3lb1oz

So last week i swapped em out... Timney in the Sport... CMC into the 15-22

Well today I tested it out..at 1st it was real nice..... can really tell the Hammer Spring Difference... feels like more of a POP when ya pull the trigger.
Then I tried some mag dumps... hmm not so good... BUT... reason was me... with the Heavy hammer my technique needs to change... i actually needed MORE umf on my forward pressure.
So tried again.... FREAKING awesome.... Full dumps.. no issues

then some Bursts (harder to do with the Timney, i would get FTF) easy ta do... actualy, due to Heavy hammer, thought i had FTF's.. then i'd pull the trigger and BAM... so realy easy to do Bursts with the CMC

then the FINAL Test..... Dropped in the 50rd drum and LET HER FLY.... OH YA BABY....full dump... was SWEET!!


So Anyone looking for a trigger for the Slidefire..... CMC all the way... timney is Nice... but the CMC is way better


Oh and a side Note... i have the Slidefire Reverse Muzzle Break... cant really say that it does much..... but i have it

I still use mine on occasion.. Now that ammo is easier to find, I find myself doing maybe a mag dump or two every once in a while

I bought one and put it on a 15-22. I had a stock of Blazer 22, bought many years ago. It won't work with them, it needs more "Pizzazz", so I dipped into my stash of the much maligned Thunderbolt which work OK.

Ya mine used to be pretty finicky, but after some work it runs pretty reliably with most anything. The cci mini-mags still work the best though
