Vltor 5-Position Receiver Extension MIL-SPEC

... Inside and out. None of the machining marks that I've read of on/in other manuf. extensions. Easy install, works perfectly. And as always, exceptionally fast service from Primary Arms.

exactly what I ordered and fit perfect. However, the numbers on buffer tube are not visible at all with ACS stock Adjusted to my arm length when rifle is shouldered. This buffer tube although fits and functions well it is not designed for the Magpul ACS stock.I am happy with it anyway.

Excellent product. Runs flawlessly on a new mid length build. Primary Arms shipping was lightning fast halfway across the country from me!

If you need a tube for an AR build, this is the one to have... there is no equal. The fit and finish are perfect...period!

Solid addition to my AR to go along with my Vltor EMod stock!

This extension is well built, but I wouldn't expect any less from Vltor.

this is a good product

Top pick for a 5 position rec extension. I have no requirmeent for a 6. Only VLTOR stocks have the little window to view the 1-5 numbers, as far as I can tell. Imod-yes, Magpul and basic stocks-no, if that matters. Fast shipping!

This is an excellent piece of equipment in both fit and finish and asthetics. It works excellent and was bought at a great price.
