I've been following my own advice on buying more ammo, perhaps now is the time to follow my own advice of buying more guns. Up until recently I've been a large 2A supporter, but not a large gun owner.
I have a few handguns and a few years back, got a shotgun, so now I'm thinking about getting a rifle. I've been leaning towards an AR-15. An appealing part are the large selection of 80% receivers as that would mean less of a paper trail. I'm particularly interested in the 80% poly receiver kits that appear to only require a drill to complete. Would be nice to see if it could be under $1k. I got a bit more research to do. Any advice is welcome.
Anyways, happy Sunday Gunday!
Don't bother with a polymer 80% lower that mimics the external dimensions of an aluminum lower receiver: the dimensions Stoner used were made with the tensile and compressive strengths of aluminum in mind. Using FRP or other polymers usually ends with the buffer tube mounting boss cracking and breaking off where it connects to the rest of the lower receiver.
Be prepared to spend a fair amount of money over and above buying a stripped 100% lower face to face (assuming you live in Freer America where private party transfers are not required to go through an FFL) as you're looking at a couple of hundred for a decent 80% jig, then a couple hundred more for a router/drill press/mill (well, any mill that runs a couple of hundred new will be "meh" and very low end, but will suffice for milling out the trigger pockets on a lower with a good jig) and the bits, and other ancillary tools. The up side is you can finish multiple lowers, and the better jigs will allow you to do AR-15 and AR-10 80% lowers.
In the case of using the enemy's resources against them, there are a couple of decent 80% build groups on BaceFook that often have people sharing tips, and selling off tools and such.
