What I've got: - Tactical Solutions complete .22lr upper. Flattop upper, A2 flashhider, 16.1" 1:16 twist barrel. Stainless steel BCG (makes it so very easy to clean!) Currently has a MagPul MBUS Gen1 sight for the rear and standard F marked FSB. This upper has proved itself reliable with just about all the ammo I have tried in it. The only exception was Rem. Golden Bullets, which are crap and TacSol specifically advises against using. - Denny's Guns (Global Tactical) AR-15 lower with mil-spec receiver extension and MagPul CTR stock and MOE grip. Denny's lowers are made by Tactical Innovations, and feature a setscrew to adjust the tension between the upper and lower receiver. The castle nut has some marks from me staking the castle nut. - (4) Black Dog Machine 25-round magazines. These are currently the best mags out on the market for the .22lr conversions. I'm looking to either sell/trade the upper and magazines, or sell the entire kit. For the entire kit, I am looking for $825. For the upper/sights/magazines, I am looking for $525. Trade interests are S&W M&P series pistols, Glocks (9mm or .45acp only) and tactical shotguns. ETA: Only interested in selling within Oregon. Prefer to be to someone with an Oregon CHL.
