    The quality I've come to expect

    BCM has yet to disappoint. The quality in fit, form and function of every part has exceeded my expectations with every part.

    Very tight tolerances....

    Nice finish and there is no doubt it is robust. Feels and looks like quality stuff for sure. Definitely had to heat the upper to get the barrel extension to fit. Was a little disappointed that the rear pin will not go into my Larue billet lower without a fight. Probably just need to work off some material but the upper easily fit a Wilson Combat billet lower but there is some play there. I don’t feel like that’s the upper at all.

    Best of the best!

    I have always used BCM Handguards always perfect but the rail on my uppers were always a little narrower, so this time I got a BCM Handguard and upper, finally the perfect match. I will never buy anything else. Bravo company all the way!

    High Quality Product

    When you want a receiver to be right every single time and not wonder whether or not QA/QC received to attention, buy a BCM receiver. I couldn't be happier. BCM has a new customer here.

    BCM M4 Upper

    BCM has quality products. The upper I received from them meets my demand for quality. I only wish they would sell stripped uppers, then I would be happier then a pig in a mud hole.
