Combined with the mid-length gas system is an H buffer weight and a Sprinco blue recoil spring making this pistol soft shooting while still being reliable.

Picked up this Patrol Rifle Three XL from Primary Arms a couple months back and finally made it to the range to report back with a review. First impressions were great- rifle came with range bag, M2 mag, beautiful anodizing (looks shinier and feels harder then your standard receiver anodizing), tight fit between lower/upper receivers, properly staked castle nut, QD end plate, Sprinco Blue/H1 buffer, Magpul PROs, ambi Radian Raptor CH (Standard latch, not the plastic LT), beautiful NP3 carrier with nicely staked OCKS fasteners, polished NPT trigger, and ambi safety. This is the first fully built AR I’ve purchased (typically build my own to reduce wasting money on swapping parts) but the specs sounded great right out of the box. Added an LPVO, light, sling, Dead Air brake/can, JP enhanced trigger spring kit, and Sprinco red/H2 (was slightly overgassed when suppressed) and now this thing is ready to rock. Overall great value for and quality for a rifle ready out of the box.
