Something I learned a while back that has helped my WE HK416's bolt catch issues.

Take an AEG shim (Yes, the little shims you use to shim your gears) and put it between your bolt catch and the posts it sits between. It works wonders.



The bolt catch wobbles a lot which tends to let your bolt slip right past the latch - Poorly fitted parts tend to wear quickly. How long does a poorly shimmed gearbox last compared to a well shimmed one - This applies to GBBR's too.

I run stock WE bolt catches, they get me much further then 20 mags. Ran the first one for 3 years, changed out to my second one and been running it ever since. No filing or any of that BS. Not knocking RAtech, just saying that this may prolong the life of your bolt catch.
