Questions & Answers
I have a 300 blackout with an 8.5 inch barrel, low profile gas block and a pistol length gas system. Will I be able to use this on my rifle?

I use this on an 8.3 BA and half of my muzzle threads are inside the rail, I run just a thread protector, but the openings of any muzzle device still fall past the rail, if you're going for a can you'll need to make sure it stands off slightly from the shoulder, but you can get that nice seamless look.

Perfect match by GD, Verified Owner, April 5, 2026
Bought this to close the gap from rail to suppressor. Works perfect with an 8.5" barrel with 1 shim. Finish and quality are well worth it. No worries with stripping the screws like a lot of the cheaper options out there.
