The quality of this kit is excellent as expected from Midwest Industries.
I’m using it for my blackout pistol build mated to a Noveske lower and a 12.5 “ barreled upper. The kit was coupled with the SB Tactical brace where fitment was tight enough to give me extra length of pull leaving a gap not pushing it to the froward stop. I’m using electrical tape around the tube to keep things extra tight and in place to prevent any movement. I like the kit so much that I purchased another kit to replace my KAK blade. I replaced the plate with sling provisions for HK clip. Job well done for Midwest Industries!
