I just joined the NFA Club :)

I finally received my SBR and Suppressor tax stamps about a month ago. It was about an 8 month wait. I finished putting together my Suppressed .300 BLK build. And took it to the range for the first time last weekend. The build was with the following parts:
-R-Guns lower
-PSA Moe lower parts kit
-Spikes tactical upper receiver
-AIM NIB bolt carrier group
-AR Stoner 10.5" SS barrel
-Noveske low profile gas block and tube
-Midwest industries 9" G2 rail
-Magplul MOE angled foregrip
-Vortex Spark red dot sight
-Rainier Arms RMC compensator for when I'm not using the Suppressor
Keechi Creek Arms .30 Cal Suppressor that was built by a local gunsmith in my town.








When I took it to the range last weekend I was please with this other than the heavy trigger pull from a standard lower parts kit. I think my next purchase will be an upgraded trigger, maybe a RRA two stage. With 220gr subs it sounds about like a paintball gun.

Check that Stoner barrel for suppressor alignment with a polished land-diameter drill rod (McMaster Carr 0.2969 +/- 0.0005") before you assemble and fire it!

I'm in a 3-way conversation with Midway and Stoner (Stoner refused to reply to my messages until Midway got involved) because I did not have my suppressor until a few weeks after I built the rifle.

Despite being a lightweight taper, I get a consistent 1.25 MOA from the barrel. I hope the replacement works just as well.

I just took the pictures this morning and was going to call Stoner today (Midway told me Stoner wanted pictures but I had too many meetings today to call). Will call Wed. morning.

Thanks for the heads up Arizona Mike, but I already took it to the range and fired it last weekend. Maybe it's a good thing that my suppressor has plenty of clearance, it would have sucked to have a baffle strike my first trip to the range with my SBR and Suppressor. That's surprising to see, all of the reviews I read of 10.5" SS AR Stoner barrel were good. I'll look into ordering a rod like that to check it. How do you know if it's the suppressor or the barrel that don't have concentric threads? It seemed to shoot well, at 50 yards I shot groups that were about 1" across and at 100 yards groups that were 2 to 2.5" which I'm happy with considering my sighting system is 2moa red dot.
