My favorite upper

I love the piston system and how clean it is. Accuracy is great and I like how smooth it feels. If you’re thinking about getting a new upper, THIS IS IT.

It works flawlessly right out of the box. Attached it to my lower I built on my own. Good length and balance. I added some attachments. I added a M-LOK QD Swivel mounts so i can use 2 Point Rifle Sling, Magpul backup sights, and the Burris TAC30 which is a close quarter tactical optics kit. It looks great with the upper.

Fired approximately 200 rounds at the range last weekend. Very accurate. I was able to get tight groups at 50 and 100 yards after zeroing it in. I like the matte finish. Recoil is good and very manageable. The Radian Raptor LT Ambi Charging Handle is very smooth. I have not gotten a chance to use the adjustable gas regulator. I also bought a PWS Compensator since flash hider is not allowed in California...

This was my first rifle build and i am very happy with how the upper performs. I highly recommend it for those who want to build an affordable and accurate rifle.

Absolute best upper I've ever used. I've used scars and daniel defense rifles over seas, but they dont compare to this thing. Affordable and insanely accurate. I attached a strike industries brake and this thing shoots stupid flat. I swear the barrel is capable of .25 moa because I was able to shoot a 400 yard target while standing using a leupold cq/t on 1x. That's a 9moa dot on a 400 yard target! And the very first shot was a hit.. this upper is a must for anyone who enjoys shooting
