Adams Arms 7.5" P2 Piston Drive Folder

I’ve never been an AR guy. Cleaning DI guns soured me a long time ago.

That doesn’t mean I don’t appreciate their versatility and flexibility. In fact, I am usually adapting AR features to my other flavors of weapons. Then, one day last Fall, I walked into a LGS and picked up a Barrett rec7 piston driven pistol. It was love at first sight, but nay, we weren’t meant for each other. She came from an upscale neighborhood. One that I could never afford…

So, in the finest of Weird Science tradition, I made my own.

I dialed in the cycling with an Odin Works adjustable buffer. Money well spent. Then I modified a spare buffer for the desired weight and put the adjustable back in the tool box.

It is running like a sewing machine and a literal blast when shooting steel. The pics show a Troy muzzle device. That has been swapped for an SEI comp that actually eliminates the fireballs from the 7.5" barrel.

My total cost came in $400-$500 under that Barrett rec7 I saw.
