AR Stock Block

thingiverse

Part to fit MIL SPEC Buffer Tube holes converting collapsable stock into fixed stock for those living in non-free states. All you have to do is print this part with 100% infill and cut it to length. Printing at 100% is actually faster on my printer and helps keep the strength high. Make sure to print the flat side down and the round tab side up. First, remove the stock only, leaving all other items on the buffer tube in place. If you like the full-length stock, cut the last hole block at the very end as close as possible to the block itself. If you prefer it a bit shorter, measure and cut the bar so that it fits just before the hole where you want the stock located. Then, on the other half, trim the bar so that it is just after the hole. They are designed to fit very tightly, so use your armorers mallet with the white plastic side and drive the bar into the holes and the channel. Then slide the stock back over, and you're done.
