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.

Midwest Industries 8” Combat Handguard by JNC, Verified Owner, November 15, 2023
I own several MI rails and they’re all great. The 8” Combat rail I purchased was put on a 9” SOLGW 300BLK. The fit and finish are great. It’s very rigid for a light weight rail. The install was very easy.
