Early on at 308ar.com we did a page that referenced the the point that the Armalite AR-10 utilized a BOLT CATCH ROLL PIN same as the Armalite M-15 (AR15) rifle while the DPMS LR-308 308AR and similar rifles utilize a BOLT CATCH SCREW. Well despite that page we still get many questions about this small part. Based on these messages I decided a simple picture might be easier to understand in this day of sort attention spans. While I believe there are a small minority of 308AR manufacturers using BOLT CATCH ROLL PINS just as there is an AR15 manufacturer or two have adopted the BOLT CATCH SCREW feature. This post is meant to make folks aware of the differences.
