I would think it is ok to offer AR-Spoon parts for sale here.
I have a black Magpul PRS stock. Basically like new. I'll sell for $200+shipping.
PRS™ - Precision Rifle/Sniper - PRS™ Precision-Adjustable Buttstock – AR15/M16 (5.56 NATO) Model
I got some other small parts like an oval M4 forward handguard in green, a David Tubb adjustable buttplate that will fit AR-15 or bolt rifle stocks (might require trimming the bolt rifle stock a little). I got a bunch of GI M14 20-round magazines too.
I'll post some pictures later.
