    They are pretty good. The receivers are said to be very good for doing builds on. The only real problem with them is some of the threads (dont remember what ones) are different then "mil spec" so not all US parts are interchangeable.

    You can get a good used SA M1A for under $1500 easily if you are not in a hurry (I know the market is high right now but still). Others may disagree but I would not put a value of more then $1000 on it. Again that is what it would be worth to me and why.

    i think the issue is bbl threads to receiver and flash suppressor threads are metric. i couldnt swap bbls on mine nor get rid of the evil non functioning poly style flash supressor.

    There was also an issue with the receivers being softer than GI ones. Fulton Armory used to do an upgrade on these rifles that would bring the receivers into spec and replace some parts with GI parts. I'm not sure if they still do but when they did it was quite expensive. I found that I was better off spending the extra $ for a Springfield at the time.

    All the stuff I have read it is the bolts and NOT the receiver that is the issue. The poly's have a forged vs cast receiver. There are tons of threads about putting a few USGI parts in the poly's to have one awsome gun.

    For the traded of a Lo Pro I would have done it. Plus I know Eric has been looking for one and this was the time for him.

    Nwcid is right; the receivers are fine. Problem areas on SOME Polytechs are the bolt, the trigger group, & rear sights, which are sometimes soft.

    The bolt is the most serious, as the lugs may not make good contact with the receiver. Also, headspace may be excessive, & firing can further increase the headspace. Either of these problems could lead to catastrophic failure if undetected. Lot of owners change to a USGI bolt, which requires an expert 'smith to install.

    For $100 they will fix the receiver to accept GI bolts. That tells me that the receiver is out of spec. Also I remember being told when I called them that they recommended heat treating the receiver to harden it.

    The only reason that they have to fit the GI bolt is because the lugs on the M14S are manufactured smaller, the barrel can accept GI barrels the difference is there is a socket head screw to lock the barrel in place. I am not sure about the flash hidder threads, I have a GI on the rifle I own. The receiver is fordged and as stated before is a good place to start building a good rifle. I have a friend that has a rifle that has no modifications to it and he is on his second bolt only because of the number of rounds he has put through it.

    The comments in this post reminds me of the comments that start flying around when some asks about a third generation Universial carbine.

    The bolt locking lugs and the lug recesses in the receiver are shorter front to rear than the GI/Mil Specs.

    The PolyTech front sight post is taller than the GI post.

    Trigger groups are interchangeable.
