So I got the new cap a last week...shot it, works great and all...fastforward to today. Some buddies and I go shooting at the Plaqumines range. And BOOM another endcap strike! I think it happened when my buddy was shooting my G19. The only way i can think that would have happened is it started to loosen while shooting and of course he didnt know to check it every few shots. I should have payed closer attention. Lesson learned. The newly damaged cap looks almost identical to the pic US Infidel posted.
