Pleasantly surprised


Was concerned at first. When rifle arrived it was super light to me. Then when I geared it up with all my usual accessories everything felt normal. Took to the range and was able to put in some awesome groups at 50 and 100 yards. I'm sold on this one.

Excellent rifle!


Highly impressed with lightweight and the cycling process.
<br>Added some attachments and still weighed less than my other ARs. Ammo (Sellier and Bellot) cycled properly; no stoppages or failures. Shot tight groups for zero at 25 yards. Highly recommended! Kudos also to Primary Arms for quick delivery!
