Thanks for the piston AR advice

[Autopistola]

After reading a lot of piston AR threads, I followed the most common advice:

Just buy a BCM.

(I still want a piston AR)

Last summer I got a BCM deal on a 16" middy upper with Mod 0 comp, BCG, and MOE handguard for $480 shipped.

You got a piston. It's in the carrier instead of being relocated to the gas block

Technically, blowback actions are piston also (the empty case is the piston), but for clarity we call them something else...

Actually, there's a marketing idea! Rebrand the DI setup as "coaxial piston operation".

Don't forget the 'up price by 250%' while at it.
