Bushmaster makes "Carbon 15" rifles with a plastic receiver . . . that should give an indication of how much stress it's under. I guess as long as the recoil spring & buffer can stand up to the bolt's motion, it's fine.boomerang wrote:Did he mine the metal himself?HankB wrote:This link is a lot closer to what I consider a "scratchbuilt" AR![]()
How strong does the lower have to be? Does it do anything more than hold the buttstock, trigger group and magazine in the right place? Does it it have to be one piece?

Re: AR - from scratch
G.A., where did you find parts that easy? I didn't know there was a place in Lubbock that carried loose parts. I've looked at Sharpshooters, and Fred's before with no luck. Last time I was in Lubbock, I went by Texas Tactical, but they were closed with a big sign on the door that said, "Closed until further notice." I need a few parts right now but I've been waiting till I need more stuff so I don't have to pay shipping several times.

Re: AR - from scratch
Here's a good buyer's guide but geared more towards duty rifles for LEO types. It may or may not apply to the casual AR-15 shooter.

Re: AR - from scratch
Sharpshooters had the parts I was looking for, and they actually had them at a good price (the parts kit was mis-marked they want $59 for it now) and the stock was used for $24). I love the selection that sharpshooters has, but their prices usually leave something to be desired. Tx Tactical was late getting their FFL renewed, but will re-open better than before when they get it in. He is getting a few more guys to go in with him so that means better (read more consistent) hours, more inventory, ect. The guys at Outfitters supply in Brownfield can get you anything you want, but will probably have to order it in.Tactical_Texan_CHL wrote:G.A., where did you find parts that easy?

How do you explain a dog named Sauer without first telling the story of a Puppy named Sig?

Re: AR - from scratch
Thanks G.A. It's been a long time since I looked at Sharpshooter's for parts. They didn't have anything at all last time I was in there, so I hadn't been back in awhile.

Re: AR - from scratch
+1 - Did this last night myself. The directions on AR15 were great. Used a DPMS lower with RRA parts kit and trigger. If you can read, look at pictures and pick up a spring with your fingers, you will not have any problems building the lower. If you give yourself an hour, you'll still have time admire your handywork at the end.stroo wrote:I followed the directions on the AR15 site carefully. While it looks overwhelming if you go through them screen shot by screen shot, it really is pretty easy to follow.

Re: AR - from scratch
If you really want to build one from scratch, I have a few raw castings. Just machine away the parts that don't look like an AR lower
Or heck, I guess you could get some bauxite ore, a smelter....

Re: AR - from scratch
you can get a complete lower for around 250, then spend a little over a grand for a gas piston driven upper and you got yourself a nice rifle that not many people have for under $1500. not to mention no heat transfer so it'll probably outlive you and your grand children and any new gunlaws that come in effect from now til the end of time.
j/k bout the last part.

Re: AR - from scratch
There are some great videos at http://www.lifelibertyetc.com/RangeBag.aspx one of which is assembling a stripped lower.
