I was trying to make one that was not a take down. IE the receivers would be bolted together, and the barrel secured similar to an AR. Never got around to finishing it before getting the axe. I was going to rethread the barrel end, machine a threaded sleeve that could house a proper barrel nut, either use a regular 9mm AR barrel and modify an ASR bolt or something along those lines.I hold onto my two with the intent to fix them properly (i.e. not using TNW for anything), because when they run right, they're a lot of fun.
Great concept. Sh1thouse execution.
If I were to try to sell them, I'd have to ask scrap metal pricing otherwise.
I can still recall all the issues, even though it's been years.
The ASR has a double stepped chamber which causes a ton of problems. Feeding is a PITA. It's there as TNW likely never cared to actually find a proper weight buffer to ensure case ruptures (they literally use the same buffer for all calibers except 22). So if the case ruptured it would within the stepped portion of the barrel. Great idea, poor execution. Not to mention the barrel nut is aluminum (6065 or cheaper) with a hardened steel detent that keeps it from rotating out under fire. Too loose, the barrel walks out, too tight it literally strips the threads on the barrel nut. This was a huge problem, though the barrels were green mountain and of good quality, the barrel nut system would never allow for anything decent in terms of accuracy. The bolt guide screws are simply a McMaster Carr part, not that that's a big deal, but they aren't even close to identical in nature. The holes machined in the upper are deeper than needed to make up for the screws tolerances, I think, that or they just never thought to actually measure anything. Anyways, because of that combo of variables you could bind up the bolt or not have enough threads to actually guide the bolt. Usually they would be loctited somewhere in between in hopes they don't walk out or in so as to sort of work. The screws that hold the two receivers together, yep more mcmaster bulk screws. Combine those intolerances with TNWs machinework, the receivers rarely ever aligned well enough to be snug without something being misaligned. The would often never be fully screwed into place as they couldn't be, if the were, chances a drill bit was run through the lower receiver holes to cut into those screws to allow the pin to seat.
Thats all I feel like typing for now!
