Ammo Cost Savings!

[BRL40]

Yea at one time I had a CMMG dedicated upper, but I probably needed money, that's how I know that the one I had was about twice as accurate as this kit, but this kit is plenty accurate enough for my plinking purposes anyway.

The way we plink is to put plastic bottles on the ground around 60 yards away and shoot the dirt just in front of them.
If we actually hit the bottles they barely move, but the shotgun blast from the dirt and debris smacking them will send them into the stratosphere!

That is why the conversion unit provides enough accuracy.
But we also do some informal paper punching out there so I want to see if I can get a bit tighter groups.

Putting together a CMMG type deticated upper with a CMMG .22LR barrel with the proper collar for the conversion unit.

BIG FUN!

ETA: I got the .22LR upper put together and am going to freeze my tail off testing it out today.
I have plenty of 5.56 but I have plenty more .22LR so the new upper will probably get much more use.
Sorry for the sideways picture but I forgot how to straighten them out so just turn your head sideways and it will be fine.

With the money I saved not buying a kit, and the recent $75 rebate, I bought a 15-22.

And you now have an AR type rifle made out of plastic.

HA!
You're cruel!

I dressed warm and didn't even notice the cold.
The rifle was perfectly reliable and while not quite as accurate as a CZ 452 or something, it does group tighter than my conversion unit already.
I was using CCI Blazer but I still have about 4 or 5 other brands to try out.
Overall a great day, and seeing as how my gun range is about a quarter mile away from my house, I be right back out there again today for more testing.

...yea I know, tilt your head sideways.

I bought the CMMG kit and it was fun but if I shot Winchester or Remington ammo, the gun would get dirty after 75 rounds or so and start jamming. I think it did better with CCI ammo, but would still get dirty eventually and jam. My main issue was when I wanted to fire 223 ammo I had to go to the trouble to re zero the scope and just preferred using my dedicated 22 rifles for leaking with anyway.

 

[BRL40]

I hear ya.

I was getting two different points of impact between 5.56 and .22LR in my rifle, so my solution was to use two different scopes.
The red dot for when I was using the conversion unit and the scope was adjusted for 5.56.
That was easy because I have quick disconnect mounts on both so changing them out took two seconds.

Right now I have the scope on the .22LR upper for accuracy testing, but will switch to the red dot when that is finished for just plinking around.

You need a metal AR lower to handle the 22 recoil?

Geeze about time somebody posted here, and the answer is yes.
Watched a YouTube video where a guy shot a group with a plastic lower and then hung a sandbag from the barrel and shot a second group.
The point of impact was noticeably lower for the second group.
Lesson: Don't be hanging sandbags from your barrel and you'll probably be fine.

HA!

That's not it at all. It's the weight of the person firing the gun. I have proof. I let my little grandson shoot it and the accuracy comes right back. Immediately!

 

[BRL40]

I can see that but this rifle does double duty as an original 5.56, so I wanted to keep it all aluminum to come close to original weight and configuration.

Not really sure why but I like it a lot so far.

HA!

Come on you guys, that was my attempt to add a little humor to this formally stagnant forum.

Where's your Christmas Spirit?

Oh yea, since I will be shooting mostly .22LR, (5.56 price increases etc.) I decided to swap in my favorite Areo Precision handguard to my dedicated .22 upper.

I'm liking it!

ETA: The upper receiver itself is also a Areo Precision and it fits my lower as tight as my original. (zero movement)

Couldn't be happier!

When I want to go AR 22.........My S&W 15-22 does the job.

Fine, I'll play.

When I want to go AR 22.........My AR-556 does the job.

I already had one.

...and it's all aluminum.
