I purchased this for my Sig Sauer m400 tread. Fits fine like i suspected it would. The mcx style lowers are very similar to standard ar15 lowers and even more so the m400 tread lower. I will say that when shooting off hand i am not able to drop the bolt using my left index finger. The paddle now requires more force to release the bolt. My left index finger is not able to depress the extended paddle due to this.

Worth every penny. The only thing missing from the MCX was an ambi bolt catch and release and Park Mountain Machine answered the need. It is tight and stays out of the way when shooting and makes mag changes and locking the bolt back a breeze. I recommend this product over and over and over again to anyone who owns an MCX.

Incredible Quality. Seats firmly in the Rattler’s bolt catch slot. I have other BAD levers from common manufacturers and they don’t compare to what PMM offers, the others typically don’t seat firmly or end up loosening overtime. PMM’s has maintained its firmness after months of use. Highly recommend
