Lantac Cmmg Custom

[AR15]

I think you have John.
The early mags had weaker springs. The feed lips are cast and depending on the batch there can be a lot of excess flash, this can cause binding in the area that the plastic core meats the feed lips cap.
The followers front 'leg' can tilt and interfere with the spring. A quick cure for this is to cut down a .223 case and slide the base over the end of the spring, it will stop the leg from pushing into the spring. It reduces follower tilt very slightly.
I have found running SK lubed ammo helps a lot and applying dry lube to the core is a good idea.

I have found the CMMG evo mags to be really hit and miss. Some work great and others are a nightmare. Any form of resistance inside the mag and the follower spring will not have enough strength to push the bolt catch up.
Running the lighter bolt catch spring or cutting one down helps a lot and we do that an all the guns, both CMMG and Ravens. However I sometimes feel I'm fighting a loosing battle with the CMMG mags.
BAD Levers add to the problem as they increase the load on the springs. CMMG state that there rifles will not work with them but they will with tinkering.
The bolt hold open actuator can also get pinched between the upper and lower, even the slightest flexing will cause the catch to jam and require yet more force to operate.
I re-shape these to make sure the fit is good.
The mags are not very well designed at all though.
I'm currently working with a mag manufacturer and have designed my own follower to fit in their magazine, this will allow bolt hold open functionality in a very consistent product. These things take time though.

Well keep us updated on your mags, will they be black like the BDM X-forms? Grey would look so odd in my AR.
