5 of 5 Perfect!!! October 23, 2020

I could not ask for more!! This upper is incredible, it looks like it should be triple the price. I appreciate that MAS Defence keeps there prices affordable. I also own one of their 300 blackout uppers, and that one is also amazing. I love the fat handguard on this thing, it is surprisingly light weight for it's size.
