Good tube for a great price.


Great tube for the price. Works great.Only complaint is the finish, it's a little glossy.

Works great on my AR10 (308/7.62)


I am building an AR10 piece by piece and looking for the cheapest parts I can find for the original build. This buffer kit allows me to use AR15 stocks on the rifle which gives me more options on styles and prices. Please note that you have to purchase the Radical Firearms .308 Carbine Buffer before you can do this!
