I hope to reply of all the questions.
The kits are supposed to be good condition and the barrel excellent condition.
The receivers are made from a machinest in Ohio who makes hard to come by receivers, after he is done with the AR70 project as he claims he will be working on SIG PE57 and or AMT's, which I already have kits for both, and really want one bad.
I know you can not use AR mags he has mag kits for 70.00 and you can get compliance parts for also.
Not sure what ORF means.
I am going to buy one of these kits and recievers, I do not know how many this guy has, and I am jumping on it.
Here are some of his compliance parts:
44460 Compliance are as fallows; Sear $20 Cocking handle $40 Pistol grip $25 Butt stock $45 Handguard $40 Mag follower $3 Mag floor plate $2 Barrels $150
I will ask him how many receivers he has and let you guys know.
