The BCD is everything you want it to be and more, but let’s be honest that is no surprise coming from the guys at PMM. This little nugget of gold turns your MCX even more into the ultimate flex as you shave precious micro-seconds off of your reload times, while simultaneous causing range bunnies lust over you as they gasp and proclaim in pure ecstasy, “I can’t believe he just did all those functions with one finger!” This however isn’t just a story of the pure badassery that is the BCD. I know turn your attention the excellence that is the men and woman of PPM. Picture this, a sad version of the disease-ridden apocalypse we have all secretly dreamed for after watching 28 Days Later a few to many time kicks off. In all the confusion toilet paper because the new currency and business across the nation shut down as people feared for their own safety. In such a time PMM could have closed their doors, but instead risked it all and stayed open to insure the people had what they needed. It was during this very time that I ordered the BCD so that I could better defend my stash of Charmin Ultra Soft, but in my hasty installation I snapped one of the screws rendering my BCD useless. In pure embarrassment of my actions I reached out to PMM about my mistake, and behold within day I receive a new rear plate and four addition screws to assure I did not make the mistake again. They could have simply ignored my plea, but during the flugaloo of 2020, their amazing customer service shined through. I salute you PMM, if you’re ever on my neck of the woods, there’s a cold beer and a roll of toilet paper with your name on it.

It took a long time to get the right one. I’m the type that will spend the money, as long as it’s…once. Well, I purchased 2 of these BCD’s.
When received, I immediately tried the install on my MCX Virtus. It wasn’t happening. I was devastated and in disbelief. I emailed and the response was that it will work, ya gotta
r e a l l y press them on. So, I did, still no luck. More discussion ensued. Then I really !!! pressed them on!! Ah-ha…now I got it. Thank you God. Nice, tight & firm without any hinderence at all in function. Smooth and really nice. Works great for my Sig m100 as well. A slight amount of play but not enough to make me nuts. And I’m a perfectionist. Long story but all true and not a sales job. Highly recommend. I LOVE supporting American business.
