The Big Brown Truck brought me something long and black today. Details and pics to follow.
Nevermind - Talked to Spike's and they said the bolt/extractor is functioning normally and should be good to go once I'm actually on the range with it.
Anyway, the rifle pictured is a Spike's Tactical ST-22 upper with 27 round Black Dog Machine Co. mags. The upper has a carbine length YHM rail, YHM flip-up front & GG&G flip-up rear BUIS. Spike's .22 bolt is also nickel coated which, aside from looking cool, should make cleaning easier.
I'm going to try and put a few boxes through it at the range this weekend, but we'll see if I make it. I need to stop at the hardware store 1st tomorrow so I can buy the allen wrench I need to install the rear sight.
