    well made alternate for A5 use

    received in a timely manner - same quality as the previous one I got from BCM - you can buy BCM tubes with confidence if you had any doubts. I expect it will function as required.

    Awesome

    Seriously I can’t put into word what a great experience(s) I’ve had with BCM. Awesome products, awesome customer service, fast shipping, I can go and all day. Just don’t ever sit on the fence with BCM just pull the trigger and buy whatever it is your looking at you won’t ever regret it. Bought an upper few years back and i got the best gun whenever I hit the range. Like I said I can go on. Thank you BCM!

    Works as expected

    Worked flawless with the voltr a5 buffer and springco green. Fit and finish was spot on. Def get one of these since the voltr buffers seem to be out of stock all the time.

    Typical BCM product

    BCM always does it right. The price to quality ratio is always on point with BCM products. The fit and finish is second to none, always a strong attention to detail. As far as the product goes, it works well with multiple uppers. The A5 system is an advancement, less recoil on a already low recoil platform, maintains reliability, cuts down on parts wear. I'm not a huge believer in the "overgassed" arguement, so long as brass ejects strong and consistently, I don't care what direction it goes, but instead of 2oc it's ejecting at 3oc now. It also brought the over all length of the pistol to over 26'', so I can now put a verticals grip on.

    Customer review

    Haven’t installed yet but I have a BCM with A5 system from factory. I really enjoy that one. This one will go into a custom Noveske. I could be wrong but I think the BCM tube has 1 more position than the VLTOR. The anodizing is a nice deep rich black too. Would highly recommend and would buy again.

    A5 receivervat it's finest

    Some people call it an alternative to the VLTR piece, I see it as a next level part with more slide options. Great part.
