Ratings & Reviews
Possibly the nicest, best fitting forged upper.
by Eric -
These are very nice forged uppers with a billet look. The barrel receiver is a hair tighter so your barrel extension fits in very snug with no wiggle like regular milspec uppers. Tried multiple barrels and they all fit snug . The FA assist allen head bolt instead of pin is a very nice touch and made installation take all of maybe 15 seconds. Finish is nice and even.matches well with most my lowers. A tad darker than some , but thats to be expected with any combination of uppers and lowers. It fits snug to all my lowers, no wobble or slop. I would definitely reccomend. I've used a lot of different branded forged uppers and these are probably at the top.
