Lots of people building 300 BLK rifles, post 'em here! Love those SBR's and Cans lets see 'em!

Wilson Combat Recon Tactical 16" 1:7 Barrel with Carbine Gas System
Griffin Armament 7.62 Compensator-XHP762TC
Vortex Viper PST 1-4 on an American Defense QD scout mount
Finished in GunKote Magpul Tan

It now has QD sling mounts and an EMDOM sling.

Better pics from a real camera:

The only thing that is different is the barrel and comp if you have one so you could swap your BCG between uppers when you change out calibers.

On the lower, can you use same parts as the .556? And same bolt for the Upper?

You know it is. I want to see that pistol with the can. Super Badass. I fixed the thread title with an executive order....

That is very cool. With the can, and the sights it looks vaguely MP5 'ish

That is what I was going for. The HK sights are cool, but I need to replace that Umbrella pistol grip, I have decided that I hate it. Next time I put in a BCM order I will be ordering a GUNFIGHTER grip for this rig.

This thing is too much fun.

I built the upper , AP upper receiver with a WMD NIB bolt, Diamondhead 13" handguard, low profile gas block, and 308 muzzle brake also by Diamondhead and their new polymer sight set, I like the way it matches the handguard and works awesome. The barrel is a 16" fluted 300 blackout from Green Mountain. The lower is a custom billet one I purchased a couple of last year. Shoots awesome, had to change out my rifle buffer for a carbine H2 buffer, the bolt ejected the fired round fine, just didn't go back far enough to strip the next round.

had a few guys ask me how I mounted my sling to the DH hand guard. They have a new screw in mount, works great.

Sorry, I loaded the pics from my phone, easier that way. I'll go back and fill in the details...

I may have to copy cat your upper setup. That's a very sharp looking rifle!

Mine was cheap, real cheap. And it won't get you raped and made into a range girlfriend. [wink]
 
Converted 500 LC cases last weekend, loaded up about 400 of them last night - Ran out of Lil Gun.

Took the pistol buffer tube off my build and turned it on the lathe to get it just under 1.2" OD (about 1.18" now). Started at 1.265", which made getting the SB15 installed a PITA. Didn't turn the entire length, which made a nice stop for the brace.

On the 300 Blackout pistol...

I might turn down more of the tube, to get the brace closer to the lower. Need to test fire it like it sits first. As it stands, now, it's pretty comfortable to my shoulder.

My 300 Blackout rifle build. Almost complete. Just need to make/get a muzzle device for the barrel. I'm also thinking about changing the color from combat grey to sniper grey.
