i live in central arkansas, if that was what your asking. i got a FFL that has been transferring lowers for me for decades.
AR15 parts, rifles, magazines, receivers, kits: Plum Crazy Complete Lower Receiver, Complete Lower Receivers
notice over at CT they got five reviews and one of them broke on the front pins-- these are buyers that got their PC's from CT.
some of you polymer guys need to get a 0% forging from DSA and machine one out, that is some tough/hard stuff. just try it cutting/milling with an even slightly dull bit--LOL! to break one of these you got to work your ass off.
to get a polymer that strong ain't going to be cheap. with some of these( plumb crazy) breaking just taking off the castle nut that don't inspire much confidence.
i have had a bunch of plastic firearms. a nylon 66, several glocks, i once had a bushmaster m17S, taurus OSS and a cav-arms polymer lower.
ALL of them are made with another polymer that is not brittle and they were designed for the polymer used.
the cav-arms had a few failures mostly because some gommers put rifle buffers in them that bottomed out the tube when fired. and a couple came apart at the seems probably because they wern't joined properly. the cav-arms is mostly strong enough,though the thin areas around the pins are a cause for some concern with me. it is stout enough but i don't think it is as stout as a forging.
the cav is reinforced/ much thicker and uses a built in stock to get rid of that weak breakage prone castle-nut area.
sure you can make a lower out of anything --i could probably make one out of wood and it would work fine--for a "time" , a week, month or maybe just days, hours or even seconds??--LOL
i am not slamming polymers, but any polymer lower needs to be designed for the polymer that is used if it is going to have much chance lasting very long.
not long ago there were lowers for $49 shipped, LPKs for $49 and some cheapo commercial stock kits go for $29. prices are up some, the least expensive forgings go for about $60 bucks now so you can build a forged lower/stock/lpk for what???? $140-$150?
so if you have to toss the plastic LPK your going to have the same $$ in the polymer as the forgings--
so the economics of the polymer you save $40-$50 your giving up a lot of strength and wear resistance just to save $40-$50!
what i don't get about polymer lower makers is WHY they think they have to make an exact copy of an aluminum forged part?
you ever see a automobile accident where one of these newer cars with the plastic bumpers gets hit? my old-lady hit a new caddy a while back with her old 90s "beer-can quality" GMC van. the caddy blew apart like a broken egg and was totaled, had to be loaded on a wrecker in pieces.
the 90s GMC van the plastic grill broke and lost one headlight. she drove the van home.
that 90s van ain't known for strength or having thick steel either.
sure you could make a "good" lower from a polymer, but it ain't gonna look like a forged one and you going to have to use some expensive polymers and methods to get a durable part.
so when i see a cheap polymer lower that is identical to forgings --yea i hear alarm bells--
sure it will be good enough for some but i would not expect to be like a forging or hold up like one. there seems to be lots of "IF" involved.
it may last IF you don't slam the butt down too hard, IF you don't over torque the castle nut, IF there is no bumps or binds, IF you don't get rough with the front pins, IF the hammer don't ride the bolt, IF you don't engage the safety with the hammer in the wrong position--
they seem well "fiddely" to me. i keep hearing well theres thousands tens of thousands of these out there? well if your going by that how many forgings are out there? hell we don't even know but at least 10 to one on the polymers, probably closer to 100 to 1 or more a thousand to one sounds more like it.
i have seen many forged lowers run through hell by boots, dragged, dropped, tossed, run over, then return to the range and have the hell shot out of them, next day do it again. a GI lower probably sees 50K plus rounds in its 30+ year life. many on the training units will see far more than just 50K.
can a boot break one? -- i think i saw one break and under the conditions it broke i figure any weapon would have broke.
can this polymer survive a bunch of boots? last for decades of such abuse? and do it for $50 less??
that is the questions i am asking. the maker claims it is "superior" to a forging?? i am an old native american and i say "HOW"?
