JohnnyRingo12 Posted November 16, 2020 Report Share Posted November 16, 2020 I have been studying and gathering up a list of parts needed to build one, when looking for 80% receivers i saw that they sell a blank firing gun for about 2500. The parts i added up are about that, and then i still have to machine the receiver. My question, if i hust bought the blank firing, replaced the barrel would that be all i would need to do? Or have the internals or other parts been made specifically to a blank gun. Could the barrel and internals be swapped out with F/A parts? Or would it be just better to buy all the parts and receiver and do it that way? Link to comment Share on other sites More sharing options...
Mike Hammer Posted November 16, 2020 Report Share Posted November 16, 2020 I'm sure that Bob will chime in when he sees this but it would be much easier to just get the parts and make one. Link to comment Share on other sites More sharing options...
ppgcowboy Posted November 16, 2020 Report Share Posted November 16, 2020 I am positive that internals for the blank are not swappable with full auto parts. Bob will chime in. Link to comment Share on other sites More sharing options...
pjr2412 Posted November 17, 2020 Report Share Posted November 17, 2020 You can find information by searching for Bob's post "Phila Ordnance M1 Thompson Full Auto Blank Gun"; just enter the title (without the quotes) in the search box. Bob describes the gun and also posted some photos. The design is such that it cannot be modified to function as a full auto firearm.Paul Link to comment Share on other sites More sharing options...

TSMGguy Posted November 17, 2020 Report Share Posted November 17, 2020 Owning a Phila Ord M1A1, I know the entire lower is made to GI specs including all of the internals, some of which are GI, some excellent repros. The frame will mount to any original GI or WH receiver. The Phila Ord receiver, barrel, and grip mount cannot be disassembled, and accept only the Phila Ord bolt. All other parts are GI, or GI spec. Phila Ord sold the complete receiver assembly with bolt all by itself for awhile so that customers could convert a full auto gun or FA parts kit to blank fire. Don't know whether this is still offered or not. You will be very pleased with anything you get from Phila Ord. Link to comment Share on other sites More sharing options...
reconbob Posted November 17, 2020 Report Share Posted November 17, 2020 Yes, the receiver and barrel are permanently attached and cannot be disassembled.The receiver in addition has hardened steel pins to prevent machining the receiver toaccept an original bolt. As mentioned the entire lower half of the blank gun - triggerframe and stock assy. is standard G.I. if you want to build a post-sample I recommend you finish one of my 80% machinedreceivers. It would be the most cost effective way. On the 80% receiver all of the fancyfootwork - ejection port, feed ramp, etc. is finished so all you have to do is machine thepocket for the bolt which is straight up and down machining with no special set-ups ortooling required.
