    BEST UPGRADE

    When married to the VLTOR A5 buffer system this is hands down the best upgrade I have done. I bought a few more and put them on every rifle I have.

    A5 receiver extension

    I am a big fan of the Vltor A5 buffer system. BCM makes qaulity products so you never have to wonder if what you're buying will hold up.

    Intermediate Receiver Extension

    Typical BCM—top notch, impeccable finish & runs perfect. Lightning service—what’s not to like?

    Intermediate Buffer tube

    I've used the Bravo Co brand intermediate buffer tube on 3 builds now. Absolute quality and combines well with Vltor A5 buffers.

    Great product

    The recommendation to try this product come from an instructor in a class I took, and my experience with it so far (with an A5H2) has been fantastic. Very noticeable impact on recoil/muzzle rise on the carbine gassed 12.5" I'm using it on. Will put these on additional guns.

    BCM Intermediate buffer tube

    As expected with BCM, top notch! This is a great alternative to the VLTOR tube which is ridiculously hard to find!

    Great option for the Vltor buffer tube

    I am glad BCM came with their version of the A5 tube. This is hard to find and the A5 system is a great upgrade to any AR15

    Homegrown A5

    A locally made, in-stock A5 option with a great finish and solid fit. Incredibly fast shipping and plenty of swag, too. How can you go wrong? I like to support my local shops and will be back for more.
