I just completed my MCarbo upgades, (trigger job, stainless feed ramp, aluminum peep, recoil buffer and charging handle and aluminum trigger guard).
For the most part installation went smoothly (lost the safety spring as it went flying somewhere )
and I am happy with everything except the aluminum trigger guard.
It seems whenever I fold the gun and then unfold, the trigger guard won’t fully close and I have to manually pull it down into place. The trigger guard will sometimes fully close if I quickly slam open the gun. The plastic stock trigger guard closed every time.
I am sure the spring went in the right way as shown in the video. Does anyone else have this problem or did I install something wrong or is it something that has to break in?
