300 Blackout

The 300 Blackout has been out for a while, but I'm only jumping on the bandwagon now.  I recently had a chance to shoot a colleague's work rifle and was sold.  It's been proven in the field at least on one occasion, used to stop a bad guy with a shot gun, and the round proved extremely effective.

This one isn't for work, or for personal protection (because in Canada, I would probably face more shit for using a firearm to defend myself than the bad guy who tried to do me harm).  Nope, this one was built purely for shits and giggles.  At $2 a round, I don't think I would shoot it very much though.

The only thing new here is the barrel, gas tube and hand guard.  AR Stoner 7.5" 300 blackout barrel, and a 7.25" Midwest Industries 3GM series gen 3 free float M-lok (carbine length).

The first thing I did was gut the gas block from one of my older 10.5" builds.

The barrel appears to be of decent quality.  Medium contour, chromoly, 1 in 8" twist, melonite finish

It was fairly easy swapping on the pistol length gas tube.  The rest was pretty straight forward as well.

I was going to put on a Surefire muzzle brake, but did't have one handy and didn't want to wait and order one, so I yanked a random brake out of my spare parts box and threw it on.

It's threaded for a generic "blast warden/flaming pig" device to throw the flames forward rather than out to the side.  For the record, it does not in any way reduce the report of the firearm.

I clamped a uni-mount to the receiver and the hand guard to insure it was properly aligned before locking it all down.

And that's my 7.5" 300BLK upper done.

Next to the 16" upper I slapped together recently.  These two may need to share a lower for now, until my OCD kicks in and I decide I need another lower.

With what parts I had, I mixed and matched as best as I could to clone my buddy's work rifle.  I may never do a 100% clone correct build, but I was really inspired by it.  Sorry, no pics of this mysterious rifle.

Now I just have to find some 300blk ammo and hope this thing doesn't blow up in my face when I shoot it for the first time.

More parts for the 102 - KAC Taupe A2 grip and DPMS 308 BCG, comparison with AR Stoner AR 308 NiB BCG

I've spent money on dumb things before, but this one is right up there on the stupidity/OCD meter.  

KAC M110 Taupe A2 grip.  It costs roughly 5 times as much as a regular A2 pistol grip, the only difference is it comes in a KAC box....and it's taupe.  Near as I can tell, it's basically identical to a regular A2 grip.  

It has an F stamped in there, but I have no idea what that means.  I know my Diemaco ones have the Diemaco mark in them, and I also have a Colt A2 grip with a C in it, but I have no idea what the F stands for.

The grip showed up with some other stuff, like a factory BCL gas block, and a DPMS parkerized 308 BCG.

I got a smoking deal on this BCG.  It was previously enjoyed, but saw very little use, and for that, I paid less than half of what these things go for retail.

Comparison between the DPMS and the AR Stoner NiB BCG.

Both BCGs seem decent, nothing to write home about, but time will tell which one, if any will work.

The KAC grip didn't color match the BCL receiver set, as expected.  And I doubt the spray paint I bought for some of the other furniture will match either, lol!
