Will the 9mm Bolt Catch correctly fit and function on the CMMG Banshee 200 in 10mm?

I will answer my own question and confirm it will fit/function in a CMMG Banshee 200 in 10mm.

Would I be able to use this on a CMMG MK9 lower with a Leapers UTG ambi mag release or will there be a space issue? Expert Answer

The Battle Arms 9mm Development Enhanced Bolt Catch will be compatible with your CMMG MK9 lower as it is a drop-in upgrade to the existing MIL-SPEC bolt catch. However, I am unsure if it will be compatible with the UTG ambi bolt catch as well although it should still work.

This is a well made part, is very sturdy and installation was simple. This issue I ran into was that it made contact with my Strike Industries Ambi mag release lever. So if you have an ambi mag release lever you might want to find a different bolt ...

B.A.D. enhanced bolt catch by Boss, Verified Owner, May 23, 2018
Battle Arms Development enhanced bolt catch. It went into the upper just as easy as any other bolt catch. It has a nice “skeletonized” look and pretty aggressive serrations, making it easy to locate by feel. The tab on the bottom helps a lot with man...

This bolt catch does not come with the roll pin, plunger, or spring necessary for proper installation. Which is a shame, because the primary draw of this product compared to similar "enhanced" bolt catches is the price. Once you factor in the cost of...

Not for all 9mm builds by Donald Morris, Verified Owner, June 9, 2026
This bolt catch did not work with my aero precision epc 9mm upper. The bolt holdback bar is small bent rod and would poke thru the center cut out portion and get caught. Once I went back to my standard bolt catch lever everything worked fine.

Not a perfect fit by BordertownUSA, Verified Owner, May 3, 2026
I like the added function of this item, and it was the only oversized catch I could find for the AR9. That said, it wouldn’t function in my PSA AR9 upper without some minor Dremel work. It wasn’t a big deal, but considering the price is significantly...
