Has anybody got one? I've been thinking of getting one to put on my SBR. I'm thinking it would be a loud fire breather.

Opinions, complaints, comments?

I have one and it's a rock star in terms of reliability. However, it's so freaking loud I had to have a Noveske KX5 put on it. I never shoot it indoors because the concussion is ridiculous. I have heard it can be suppressed with a Silencerco 7.62 Specwar, but I'd be concerned about beating the shit out of the blast baffle.  Build quality is exceptional in all respects. The Samson rail is very nice and easy to handle with a Magpul AFG. I actually bought a complete pistol, so mine came with Samson fixed HK-style sights, which are great, as well as a QD attachment and a small length of pic-rail.  I love mine, but don't shoot it as often as my 10.5" guns.

do it!

Looks like a little more recoil than I expected from a 7.5. What buffer and ammo are you using?

I see in your Avatar, you're in AL. I was born in Selma and spent a good part of my childhood in Walker County. I have a lot of family down there that I've never met.

Make sure all of your dental work is well done before firing it

I have fired one in pistol config and it was entertaining.

I'm still thinking about getting one. Has anyone tried any experiments with different types of ammo? Such as steel case wolf or Tula? Still looking for that little push to get me off the fence and pull the proverbial trigger and get one.

I have the 7.5" (top) and the 11.5".  The 7.5" is accurate and fun, it cycles anything I've tried including a lot of Tula. It's loud even with plugs and has a conclusive blast - I ended up building a micro length suppressor to live on it so its more fun to shoot.  I shoot the 11.5" more often and use it for 3-gun and hunting.

That's what I was thinking too. Maybe adding a Noveske KX5 or something similar to direct everything forward. But then, I've been watching youtubes with flash enhancers that look like a lot of fun too.
