Selling an Adams arms piston 308. This is factory built and is the patrol model. Retails $1,155 at budsgunshop.com. Excellent condition, I shoot my pof 6.5 Edge anytime I take out an AR10 so it’s time to clear a little space up. Excellent guns. Guaranteed accuracy for life (they use voodoo barrels) and a 100% lifetime transferrable warranty if you ever have any malfunctions. Piston is adjustable. I’m happy to answer any questions. Comes with a windowed 25rd Pmag.
