Polytech M14

The M14forum.com has a lot of information. Gus Fisher link below
https://m14forum.com/gus-fisher/89234-magazine-fit-problems.html

This didn't work for me so I looked further. What fixed the binding problem was...the chinese handguard was resting on the wood causing the the front of the receiver to sit at an angle when the trigger housing was latched.. This pressed in on the magazine well. Put the receiver in the stock and latch the trigger housing.There should be a gap between the bottom edges of the handguard and the wood. I installed a usgi handguard and the magazines don't bind. You could sand the bottom edges to get the gap. Do a search of polytech mag issues. Gus Fisher has a 24 or so step guide and Art Lupino articles helped. tonyben has a video on disassembly of the gas system and addresses the handguard gap and draw pressure.

tonyben has removed his videos from youtube. He is a moderator on m14forum.com so they are somewhere.

Polytech receivers are great, more mil-spec than the Springfield Armory receviers. The only issue is the bolt, which tends to be soft. Most people recommend buying a USGI bolt and having it worked on by WarBird Custom Guns.

Never seen a Magpul M1A magazine. Don't think they make them

You may be correct. I was thinking AR10 Mags not M1A mags..

I've frequently bitched at them on their various social media platforms to make an M1A magazine. Can get a G36 mag but not an M1A, assume that has to do with foreign military contracts. Either way I've never seen one and they don't seem to view me as a market expert

I was actually about to pick one of these bad boys up in a trade for my gen 2 night vision but the guy backed out and ended up just giving it to his father. Still bummed out about it, to be honest.

The previous owner had the bolt assembly replaced with a USGI assembly. WarBird did all the customizing on this weapon.That had a lot to do with me buying this one.

I am retired Air Force. I see you are well decorated. Thank you for your service.
I have a lot of medals from my Air Force service.
I have metals in my legs, metals in my back, and metals in my shoulder.

Sounds like a really good buy then. My Polytech is waiting to be worked on, have yet to send it out. Thank you for your service, I'm 9 years in, hoping to make it to 20.

Not that I give a damn personally but aint what made the Polys legal vs an M1A is that a USGI bolt dont fit?

The MD list is crazy. It was put together by politicians who don't really understand guns. The M1A is banned as is the M14 (of course). If you look up the Polytech M14 is is listed as not banned. The Norinco is not on the list. That means if you want a Norinco, you must submit all sorts of BS paperwork to MSP. They will in time approve or disapprove it and it will be on the list as banned or not banned.
There is no real rhyme or reason for how the list was originally put together.

One thing on the list states if a weapon is a copy of a banned weapon, but has no more than two of the military components (a folding stock; a grenade launcher or flare launcher; or a flash suppressor) and the parts are not interchangeable, then it can be approved. There is a lot to it than that, but the basics.

There were other manufacturers of M1A rifles. Some used all GI parts others all Chinese and some were a mixture. None of these are on the list and proving a metric one is not a "copy" would require parts from a GI and or thread gages.

The list is not legally binding. MSP has stated so although I lack the source document.

Norinco can be sold cash and carry still today because it has a metric gas plug. Not totally parts interchangeable with the banned M14/M1A.

Same thing with the Poly cuz that uses a metric bolt

But since his has a USGI bolt, does that now make it a copy of a M1A?

I can tell you exactly what your problem is. Two words. Pro mag. They are horrible. There is a running joke in some firearm circles no mag is better than pro mag. Go buy the Magpul

No joke. I bought 3 Promags for my 7.62x39 Vepr in PA. Only 1 out of the 3 fit. I will say, Promag was a stand up company, and offered to replace the whole mag. I explained to them I could not have a whole mag shipped to MD, and asked if they could just ship the hollow mag shells, which they did quickly.

I got a couple 20 round Vepr 308 Promag magazine in early 2013 before the ban, and they kinda sorta fit. Had to file a bit. Try some regular 10rd M1A/M14 mags. I saw some on eBay not too long ago, I'll check. They may have gotten removed.

It may not be binding, but try to get an FFL to order or accept a shipment of one that is banned on the list or not on the list and they will laugh at you!

There are other features that would over ride that one item, I think. Besides, the action says it is a polytech. I think that is as far as an FFL looks.
