Afternoon all, new poster but I've been lurking in the shadows for a few weeks/months now. My father bought an Evo carbine a few weeks into the new year and largely due to aftermarket reviews here and on YouTube he was able to install a HB extended charging handle, trigger shoe and trigger spring (after drilling out the welded screw) and a right side safety delete, so I wanted to say thanks for him and ask a general knowledge question....
Having only fired the carbine on two occasions we had some minor issues after this last trip that were easily addressed, but I wanted to see if there were any other experiences like ours.
First, while clearing the range at the end of the day we were unable to move the selector lever from 'Fire' back into the 'Safe' position. Upon arrival at home and field stripping the weapon, I found that the set screw which holds the right side safety delete in place had backed out into the access channel in the lower receiver that allows the safety levers to be removed. I removed it further and blue lock-tited the set screw in place, and actually did the same for the left side lever as well, just to prevent a future incident. Has anyone seen this with replacement selector levers? Is there a better way to solve this problem than what I did?
Second, while clearing the range and dealing with the selector lever, we also noticed that there was a gap between the front of the OEM grip and the lower receiver. Once at home I was able to remove the grip and ascertain that the issue was the grip screw loosening enough to allow it to slide rear-ward on the trunion under recoil. I removed the grip and found that the grip screw goes through a slot, rather than a hole in the trunion. I reattached the grip in its forward location and tightened the screw tension while applying some blue lock-tite (beginning to sense a pattern here?). The question multi-faceted, is there a better way to do this? Has anyone had this issue with the OEM pistol grip? Do after-market pistol grips have this issue? Is there a shim that can be placed into the slot that prevents this slippage in the future?
Sorry for the novel length first post.
Any help or comments would be much appreciated.
