Ratings & Reviews
They missed the mark on my chamber. Fired brass coming out with the shoulder 12 thou short of where it should be, and rounds that pass a Wilson gauge will not fit in the chamber.
<br>I contacted Customer service explained the exact problem and sent it back. I received it back with a note that they changed the bolt carrier group????? and it is good to go.
<br>I am contemplating buying a reamer and fixing it but that will add 170.00 more to the build.
<br>Apparently there is a reason the reviews are either good or bad. Quality control is an issue.
Some ammo doesnt chamber
Solid-built complete upper that had no wobble/problem fitting my anderson and dpms lowers. DISCLAIMER: The first ammo I tried, 140gr Polycase ARX made by Southern Ballistics Research in Brunswick GA, wouldnt even chamber. Every round sits about 4mm too far back in the barrel and the bolt wont fully close behind it. So I switched to 300gr Underwood Xtreme Penetrator which did chamber and shoot correctly.
