Has anyone here used one of the DIY polymer AR15 kids like the Freedom15 ? Any thoughts about how durable they are? I just think it'd be cool to actually roll my own but I'm wondering if I'd wind up with a useful rifle or just a novelty.

I have not, but I have done several in al. I don't see that the work involved is much different nor the tools and skill. So I can't see any reason to do a polymer one. I didn't have any trouble doing an al one the first time. “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

The lower of an AR, sees very little stress in semiauto. About the only way a lower wears out, is someone over-tightening something, or in auto, the trigger pack pin holes elongating. You could probably make one out of rock candy. Arc. ______________________________ "Like a bitter weed, I'm a bad seed"- Johnny Cash "I'm a loner, Dottie.

Seems like a neat project for a one off. But with Anderson lowers in the $35-$45 range. I'd just grab a cheapy there. At least its a forged aluminum lower. Train how you intend to Fight Remember - Training is not sparring. Sparring is not fighting. Fighting is not combat. | |||

At $339.99, the kit is kinda expensive unless you plan on making a whole bunch. If you want a super lightweight lower, Joe Bob Outfitters sells a Carbon Fiber lower for $39.95. It weighs 3.65 oz. New Frontier Armory LW-4 stripped lower | |||

The only reason I can see doing one is for the fun of it ... Not even criminals would spend that much money on a receiver, then take hours to finish it! If you really want something you'll find a way ... ... if you don't you'll find an excuse. I'm really not a "kid" anymore ... but I haven't grown up yet either  | |||

Someone should make one out of Lego Technic pieces. Arc. ______________________________ "Like a bitter weed, I'm a bad seed"- Johnny Cash "I'm a loner, Dottie. A rebel." - Pee Wee Herman Rode hard, put away wet. RIP JHM "You're a junkyard dog." - Lupe Flores. RIP | |||

Funny thought. I have a friend who is actually a machinist who has made numerous lowers from scratch (you know big blocks of al ==>to working lower). he decided as a project to see if he could make a working lower out of simple commercial pieces and shapes. you know blocks, squares, tubes, etc. No machining. Yup it looked like crap and there were a zillion fasteners, but it ran just fine. So some glued lego's might be workable. “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

I dunno if it's a kit, or just plans, but there's AR lowers that are just bolted together, like Erector sets. Disassemble it and it's just a collection of flat sheets with some holes, and a handful of bolts and nuts.
I could go for a Jolly Rancher AR.

You know, all it would take is a mold, a candy thermometer, a double-boiler, and a bunch of crushed Jolly Ranchers. You’d apparently have to get the candy to almost 300 degrees, so care in handling and a mold that will handle high temps. I’ve seen videos of people making lowers with investment casting and molten beer cans, so I don’t see why a Jolly Rancher lower can’t happen. ______________________________________________ Carthago delenda est | |||

That is not a Carbon Fiber lower. It is a polymer lower with some carbon fiber reinforcements.  Nothing but a marketing ploy. Much like the super fast speedy fiber backed internet.

that would be interesting, I do recall seeing one somewhere that was made in the style of the brazed together M1 Carbine trigger housings, basically just a bunch of plates stacked up and brazed together, fugly, but worked https://chandlersfirearms.com/chesterfield-armament/ | |||

I have always wanted to make one from a 2x6, CAV arms style integrated stock, press/glue in cut tube for bushings, rod stock for pins. Just to shut up anyone who is hysterical over the 3D printed lower. | |||

Yeah, they are pretty expensive considering you can only make them for yourself. Maybe I'll invest in a 3D printer instead.

The greatest point of stress for a lower is where the receiver extension threads into the receiver. I'd be very reluctant to pogo a stuck round out of an upper attached to a polymer lower. I've seen some polymer lowers with metal reinforcement brackets embedded in that portion. But at this point, with how cheap aluminum lowers are, it doesn't make a lot of sense unless you're doing it for the DIY value. | |||
