Thank you!

MacPherson Firearms in Brentwood. They're in that old castle-looking place that used to be a school.


Here's a pic I snapped the day I got it.

I went by the shop where you got the lower from to see about buying one. They are out of them now but will be getting more in.

I like the logo on it, otherwise It is just a different lower.

Done!

That is really nice! What kind of muzzle break is that? I went with the Troy Industries Claymore as it redirects the blast forward (Front towards Enemy).

Thanks! The entire upper was bought assembled from BCM. This is their Comp. Mod 1. I have not had a chance to shoot it but hopefully will tomorrow. That is a great photo!

Thanks MikeNH,

I grabbed that from the video. I took it out again today. At 100 yards, it range the gong as long as I did my part and kept the dot on the target!

Latest pictures. I added an extended mag release, KNS Anti-rotation pins, and a BAD Lever. I also replaced my original Holosun with the reflex version.

After my wife was done "Rolling her eyes", I got her to to film me this evening firing my AR Pistol with the Claymore muzzle break.

I got mine finished up a couple weekends ago. It's an 8.3" 300BLK, waiting on my suppressor.

I can't figure out how to resize this to a normal size, so here's a link for now.

I like that Rustpot. What kind of brace is that?

That is a SB Tactical SBA3 brace. I recently finished my AR9 with one.
I prefer it to most of the other braces out there.

Brownell's has the black SBA3 with the buffer extension on sale for $109.99 with a checkout code...plus free shipping on $99 or more...

https://www.brownells.com/hand...able-prod116831.aspx

I put the FDE (which is sold out) in my wish list for my .300 BO.

I just built one too. Couldn't pass on the $399 complete Troy 10.5 300 blk upper from Primary Arms. $29 Anderson lower, PSA build kit with SBA3 pistol brace for $149. The $399 Troy upper comes with a $170 TRX Extreme MLOK rail and $160 worth of Troy flip up sights, a phenomenal deal all in.

I have a couple Magpul and Lancer 300 blackout specific magazines coming in, and some ammo too, will try to get out and shoot it soon.

Here is the upper I bought for $399.
https://www.primaryarms.com/tr...p-battlesights-black

Edit: Shot it today, perfect function with all ammo tried, Hornady 190 Sub X, S&B 200 sub, Federal American eagle 150, Armscor 147. Magpul 300 blackout and Lancer 300 blackout magazines worked perfectly.

All ammo functioned fine with a carbine and H buffer. I'd probably choose to run H buffer for subsonic loads, and H2 buffer for supersonic loads.

Thank You Pale Horse.
It took me three builds before I got it right.
This one runs very well.
