SWS Brass Deflector is now available

[Lorelei]

I have had a hunch it would be the 45 degree all along. My home made ( not original with me) deflector consists of a 1.5" long 45 degree rail section with a length of polymer rail ladder attached. Maybe a couple of bounce backs in 6 or 7 thousand rounds. Looked crude, but it works essentially flawlessly.

I suspected the same thing because the brass never stops moving like it does with the others. That momentary stop before it dropped to the ground gave a second piece of brass a chance to hit it and bounce back in during rapid fire. At least that was my observation of what was happening during rapid fire.

I hope I didn't offend by posting here. I see that now 3 of us have had great success with the 45 degree shield. I'm more convinced now that we have a winner here.

This is the right place for it! You're in good company.

It is good to hear that you all are having positive results. It is odd, all 4 prototypes work flawlessly on my rifle. But it seems that yet again the 90° prototypes are not working out. I suppose for whatever reason my rifle has a different ejection pattern then most.

I look forward to hearing some more range reports. And again thanks for helping out with the brass deflector.

 

[SimpleWeaponSolutions]

I wonder if I can hang a little bag on it with a couple of small S-hooks ...

I was going to start working on a brass catcher, as a couple of other members had asked about me making one. The original concept I was working on would have been derived from the 1st gen brass deflector. Once everything has been sorted out with the redesign I will be moving forward with a brass catcher.

I suspect you're right in that there's some variance there. The 25 degree worked perfectly on my stock gun no matter how fast I fired but had issues in my modified one. The ejector and extractor are completely stock so I know that's not the cause. The 45 degree was perfect on both. I never compared the ejection pattern of the bare guns because I think the brass lands in another time zone most of the time.

You're welcome and thanks for letting me test these.

once you have a final product, i'm still in to buy one...my daughter is a lefty and has caught a few hot brass on her arm...she has switched to shooting righty when on the 15-22 and actually doing pretty good, but...is very uncomfortable

 

[Freeway]

Went to the range yesterday to try the prototypes.

45 degree - 140 rounds - 6 shell casings bounced back into chamber. 5 were smashed by the bolt moving forward.

25 degree - 140 rounds - 13 bounced back into the chamber. Smashed like the previous ones.

90 degree STD1 - 10 rounds - 7 bounced into the chamber. Stopped

90 degree STD2 - 10 rounds - 5 bounced into the chamber. Stopped

Maybe my rifle has a slightly different ejection pattern as well. The 45 degree was the most successful, but none worked perfectly.

That's interesting about the 25 and 45, especially the 45.

My grandson and I made a quick trip to the range yesterday and put another 300 rounds down range, 150 each. I swapped the two deflectors, putting the 25 on mine and the 45 on his. The results were essentially the same as Wednesday; I had two bounce backs with the 25 and Kinley had none with the 45.

All ammo used was Federal Champion bulk. I have not tried any other ammo.

It's interesting, the wide differences we're seeing in the testing...I have one of the originals, with over 1K rounds thru it, with absolutely no bouncebacks...I've used both federal's and CCI...

I am wondering if velocity has anything to do with the variances. Standard velocity (1,040 fps or so) should eject with less force than HV (1,200+ fps). I don't have any SV on hand to try, and there is nothing on the shelves locally.

Since I don't shoot SV anyway, it would be more of an intellectual exercise than a solution to my problem.

That may be an idea! I was using Federal Champion 36g CPHP rounds @ 1260 fps. I do have some standard and low velocity rounds I could try. Of these, does anyone have a recommendation...

Aguila Super Colibri
CCI Green Tag Precision (CCI # 0033)
CCI Segmented 32g (only have 50 of these)
CCI Segmented 40g
CCI Standard Velocity
CCI Subsonic HP

On the other end (higher velocity) I could try some of these...
Aguila Super Maximum
CCI Stinger (only have 50 of these)
CCI Velocitor
Winchester Varmint HE 3/1


I have used a lot of these, since I had a good supply, and they have all caused problems...
CCI Blazer
CCI Mini Mag - 40g CPSP
Federal Champion - 36g CPHP
Remington Golden Bullets
Winchester M-22

All of these are just over 1200 fps. So maybe I can try higher and lower. Hope this information helps!

Freeway,

Your experience with the 25 and 45 degree deflectors seems to be pretty much the opposite of what the rest of us are experiencing.

 

[Jyezahn]

Here are my results from testing. I shoot both right and left handed, but I was shooting left-handed for testing per SWS request. Ammo used was CCI Standard Velocity, CCI Stinger, and Winchester M22. For each deflector, I ran 2 magazines (one slow rate of fire, one fast rate of fire) of each type of ammo.

45 degree - 150 rounds - No bouncebacks, but had about half of the casings hit my right arm. Casings landed pretty much in the same area.

25 degree - 150 rounds - No bouncebacks, no casings hit my right arm. Casings landed in a closer grouping.

90 degree STD1 - 150 rounds - No bouncebacks, no casings hit my right arm. Casings landed almost directly below.

90 degree STD2 - 150 rounds - No bouncebacks, occasionally got hit with casings on my right arm, appx 5 out of every 25 rds. Casings landed in a slightly wider area.

For a left-hand shooter, in my case, it seems the 25 degree is the way to go. Though I did not get any bouncebacks with any of the deflectors this time, it doesn't mean I won't get some later. I have one of the original deflectors and it took me several trips to the range before I got a bounceback on it.

 

[SimpleWeaponSolutions]

Freeway, those are some interesting results.

I tested the deflectors with high velocity and standard velocity ammo.
Here is what I have used so far

Federal Automatch 1200 fps
Blazer LRN 1235 fps
CCI Stinger 1640 fps
CCI Mini Mag 1260 fps
CCI Velocitor 1435 fps
CCI Stinger 1640 fps (I really like this ammo)
Remington Viper 1410 fps

With all of this, I only had one bounce back and that was with the 25°

Went to the range yesterday to try the prototypes.

45 degree - 140 rounds - 6 shell casings bounced back into chamber. 5 were smashed by the bolt moving forward.

25 degree - 140 rounds - 13 bounced back into the chamber. Smashed like the previous ones.

90 degree STD1 - 10 rounds - 7 bounced into the chamber. Stopped

So far with the info I have gathered, still waiting on a couple more range reports, it looks like the 45° will be the way to go.

But with some of the varying reports so far, it looks like no matter what is done with the design, it will not work 100% with everyones rifles. There is just to much of a variance between ejection patterns on these rifles.

That is so very true.

I'm wondering if the slots have anything to do with the bounce backs? I have noticed at all deflectors for other firearms are slotless. Next time I go to the range I'm taping over the underside of the 25 degree and see what happens.

 

[Freeway]

The next time I go, I will try putting tape on the 25 and 45 degree deflectors and trying again. Maybe my ejection pattern is throwing the casings forward enough to catch the slots.

 

[cjt50]

Had an opportunity to hit the range yesterday. In tow, a 15-22 rifle, 400 rounds of ammo and 4 SWS prototype brass deflectors.

I have 2 15-22's, so I used my newest one. Less then 1000 rounds shot thru it and no modifications made to rifle. (all stock from factory) my other rifle is heavily modified and well worn in. I only used 5 OEM 10 round short magazines which have feed well over 20k rounds thru the 2 rifles. (well worn, but always work)

All shots were a minimum of 1 second between them. (range rules) I did sneak in a couple double taps with angled deflectors

I started off with the STD-1 deflector and shot 50 rounds of Remington Thunderbolt. On Shot #20, the bolt held open, but the spent brass was still in the chamber area and fell out when the mag was removed. I did have 4 rounds bounce back in to the chamber area, (#31, 37, 43 and 46) causing the classic "stove pipe" stoppage. I did not shot any more with it since the stoppages occurred with regularity.

Next up, STD-2; over all it was better. (but not perfect) I shot 50 rounds of Thunderbolt again and had 2 bounce backs causing stoppages. Shots # 25 and 41 were the culprits. Since I had limited ammo, I moved on...

Next up, the 25 deg deflector; Using this one, I shot 50 rounds of Thunderbolt, 50 rounds of Rem Golden Bullet and 50 rounds or Fed Automatch. I am happy to report that I had no bounce backs at all. The rifle just tick thru all 150 without missing a beat. (Thumbs up!!)

I shot half the rounds right handed and the other left handed. Using a standing stance, I tuck my arms close to my body and found that shooting left handed, my right arm was getting hit regularly with brass. I was wearing a long sleeve shirt so no burns. But the potential was there.

Last but not least, the 45 deg deflector was up. As above, I shot 150 rounds total, (same break down of types fired as 25 deg deflector) Again I am happy to report that I had no bounce backs into the chamber area and again chew thru all of them with out any issues. (Thumbs Up!!)

Again I shot half left and right handed. Shooting lefty, I did have a couple bounce off my right arm, but no where near as frequent as the 25 deg deflector.

Couple additional observations; using the 2 angled deflectors, the brass is ejected downward with purpose. STD-1/2 the brass seemed to dribble out. I also noticed on the 2 angled deflectors, there are marks in the metal where the brass hit it on the way out. The are located about 3/4 of an inch aft of the last slot (cutout) The marks are on both the side and top panels.

Over all, (atleast with my rifle) The 2 angled deflectors presented no issues. I like the looks of the 25 deg one on the rifle as it sits closer to the rifle giving it a cleaner look. (personal preference) However, if the 25 degree one is produced, it will need shorter screws since tighten them all the way down and they poke into the rail slot, actually eliminating the need for the set screw.

Hopefully next week I can test them on my "well worn in" modified rifle to verify the results.


Just realized how long post is, oppsss, (owell,,,,,)

Freeway,

Your experience with the 25 and 45 degree deflectors seems to be pretty much the opposite of what the rest of us are experiencing.

In spite of having troubles with them they're still working best of the bunch for him. I think the 45 degree will end up being the best overall for almost all of us. I got to try is again today and put 50 rounds of high velocity CCI through it with no issues. I'm hoping to have more time to try high velocity rapid fired this weekend.

 

[Lorelei]

The next time I go, I will try putting tape on the 25 and 45 degree deflectors and trying again. Maybe my ejection pattern is throwing the casings forward enough to catch the slots.

You could also try loosening the mount set screw and moving it fore or aft just a bit.
