CMMG AR15 .22LR Mk4 Evo - Lanner Tactical Version

[Dan Giliballs]

The grey mags do look more authentic, and they work very well, but the green followers they have in them did not work the bolt hold open actuator in my rifle. I had my three older mags exchanged for the evolution type, and all was good. The waffle look of the evolution mags have grown on me, plus they are more substantial in construction, especially the feed lips which are metal.

I must admit I've had a couple of instances where I've fired the last round, pulled the trigger again (not realizing I was out) then as I've pulled the mag the bolt has released on it's own accord so i've had to use the charging handle again as opposed to the bolt release button

The bolt hold open actuator fits between the lower and upper receiver. It interfaces and allows full operation of the bolt catch. Without it, the green follower of your magazine locks back the bolt - until you remove the mag, then it closes thus requiring you to manually use the bolt catch when pulling back the bolt. When you get the evo mag, you should purchase the BHOA, it's only $20 over here and is designed to work with the evo mags. The only other mod you may need to do with the BHOA is cut a coil or two off the bolt catch spring, I did, and I gain complete functionality when I use my conversion bolt.

Does it work with the CMMG BHOA?

[Vulcanator]

Black dogs will not operate the BHOA.
