    I couldnt get a competitors A5 Receiver Extension kit and so I decided to give this one a try, it is well made and structurally very solid, worked great with a JP rifle spring and Vltor buffer.

    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.

    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!

    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.

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