This was much needed! I am glad someone came out with a battery assist device for this platform that is high quality and just works.

It fits well on the original bolt release. Better than the Magpul BAD lever. I wish the black finish was more like the factory Sig finish and the construction was more rigid when I push down to release the bolt.

This BCD is awesome! Fits perfectly, installation was a breeze and it comes with pretty detailed instructions, if you read those. Would definitely recommend to get one and practice!

I ordered a mag pul bad arm that didn’t work for my MCX at all. The Parker mountain bad lever works PERFECTLY. If you want/need a bad lever for your MCX, this is the ONLY option
