Hi Grimmis, I got to shoot the Radical Firearms 10.5" blkout upper today! I actually bought 2 of them. Lol....I ran 50 rnds through each Freedom Munitions Reman 147 gr. Fmj. Had one fte on about the 3rd round. It barely got caught by the bolt. I'm thinking its from break in period. Ran nice...
I got a 300blkout upper from radical firearms, 10.5" barrel, free float hand guard, no charge handle and no Bcg. Only paid $199 for it. Had to wait about 3 weeks for it. Hopefully can try it out this weekend. I can let you know how it does if you're interested.
