Wanted to survey those of you with Colt pattern 9 mm ARs. How many of you have tried different charging handles than the std one? Which ones work and which don’t?

I have a CMMG Mk9T, and it did not like a Bravo Company Mod 4 (failures to feed). I just bought a PRI gas buster for 9 mm ARs (specific variant), so I’ll try that next week when I get out again.
