If you look at You Tube - you can load these files into a “Resin” printer to where epoxy liquid that is as strong as sheet metal in some instances - are used to build layers over a very short time. Each piece then can be cleaned - riveted or glued in place - just like making a sheet metal magazine...therefore, one does not have to worry about the availability of a manufacture stamping out 30 round magazines - you can actually print them off using a resin machine...these files will serve as a counter to the govt placing a ban on 30 rd magazines — likewise...it is perfectly legal for you to manufacture a lower receiver of a AR-15/M-4 rifle — without a serial number - as long as YOU own it. This process will create a LOWER and all you have to do is buy the upper and other parts to assemble a full - non-registered - M4 rifle. See where this is going...using composite materials and resins - one can actually make their own M4 rifle - no serial number - no over govt oversight - and it works just like the rest of them (dependent on the quality of resin)...The biggest part of getting a M$ rifle is the lower and now the almost impossible 30 rd magazine...the upper (barrel and bolt) with stock and trigger, 6 position stock, all still have to be gathered...the controversy is that, you, the citizen, could be armed with a M4 rifle and well equipped with multiple 30 rd mags where unknowing govt officials storm trooping your house will find a surprise waiting for them if it ever comes down to this...that’s why there are downloads like crazy...
with home made railguns, classic arms, etc.
I think this is already beyond regulation ability.
amunition is the next frontier in this process. with home made railguns ammunition is tiny pieces of metal.
we already have home capable lasers.
Buds Gun Store has some 30 rnd mags on sale.
