ETA: the Spike's lower with the sig brace has sold. Only lower left is the one with Magpul stock.
One rifle, one pistol. Both lowers built from stripped receivers and assembled as pistols first, so you can legally swap both of them back and forth. Uppers are as-built unless otherwise noted.
Lowers: built by me on Spike's normal ie spider rollmark lowers. LPK was mil-spec PSA (the name brand PSA, not their lower level generic brand). They have the "cap screw through the grip hole threads" trigger mod, easily reversed if you desire. Ditto with the rear take down pin detent spring mod. Threading was factory from Spike's, so no half ass home tapping here. Both unfired

and with no to very minimal finish wear. I don't think either of them have any scratches, but I'll need to check before I can swear to it. Grip on both is a Blackhawk. They pass function tests with flying colors. One has a Magpul ASAP sling plate and MOE stock.
The other has an A2 buffer tube with a Sig brace. Both with appropriate springs and buffers for their respective tubes.
Uppers: GI charging handles, AIM inside and out nitrided BCG (name brand not the unmarked and unwarrantied generic). One is V1 one is V2. Bolt in both cases is MPI Carpenter 158.
BCG
PSA Premium 16'' 5.56mm 1:7 Carbine Length M4 Profile - Blemished <--- direct from the order email. Sold as blemished, but the only issue I can find with it is the handguards don't fit as tightly on the left as the right side. Here's a link, it costs less than when I bought it now.
PSA upper Haven't had a chance to fire it.
AAC 9" .300 blackout upper, the same as here except for the BCG
AAC upper Small scratch on the right side above the rear takedown pin. It's a tight fit on both the Spike's lowers, haven't tried it on any others. I have a Magpul AFG bolted to the bottom, directly to the smooth side of the URX. Had low rounds on it when I bought it, I was told <200 and I believe it. Haven't had a chance to fire it.
If the .300 goes I also have... 5 or 6 boxes I think, of the Barnes 110 grain VOR-TX black tip ammo, generally considered one of if not the best supersonic anti-personnel load commercially available in this caliber. Loaded into mags but not cycled. Won't need it without the upper, so I can sell or include in the swap to even out value. Won't go if I still have the upper.
Ammo
I'm happy to do multiple items for one, in either direction. I can't add cash, and I have to pay taxes and transfers fees to receive FFL stuff so that's part of the equation for me. Things I'm interested in: 1911's (4.25 or 5 inch, Series 70 only) prefer Rock Island, Ruger, and Colt in order of ascending price. Very small pistols along the lines of the Kel tec P32 or P3AT, Kahr PW380 etc. Glock 19. Might be open to a suppressor. Magazines for any of them. Aimpoints (I always forget the model numbers so offer away). Decent low power (1-6 or 2-7, in that area) scopes and rings. Open to bolt actions in .270, although it'd need to be just the right deal. 12 ga self loading shotguns, an A5 or clone would be perfect, I don't care how beat up it is if it's reliable. Possibly a Ruger Blackhawk or Redhawk in .44. Good quality lever action carbine in .44, especially a Win 92 or Rossi clone. I'm probably forgetting something so feel free to offer what you've got.
