Dude, I have fired a LOT of tracer rounds through an M4 carbine; they don't do any more damage (wear and tear) to a barrel. And they are not just for crew-served weapons.

Never said they were. I said that they are MAINLY used with crew served weapons. You want to use tracers in your weapon - go for it. When I was in Viet Nam - Tracers in an M-16 were not allowed (at least in my unit).

I know 2 SDI certified gunsmiths that will tell you for a pistol tracer rounds, incendiary round, are not good for the barrel due to the added heat when firing rapidly.

So after putting it off for a year or so, my wife and I finally purchased a handgun for home defense. We settled on the Smith & Wesson M&P 9MM Shield EZ. For this first gun we wanted something my wife could handle and she shot pretty well with it when we were trying it out. I'll probably pick up something for me in a couple of months or so.

So, I decided last night after about 8 jack and cokes that I'm going to build an AR. I have the 80% lower reciever and lower receiver kit on order.

Now I need -
Buffer tube and stock
Upper receiver and barrel
Sights
BCG and charging handle

Any recommendations for parts? I'd like to keep it under $900 to build.

They're gonna sell a fuckton of those. We bought one a month or two back and have prolly only put 80 rounds through it but I'm very happy with the purchase. EZ is right, everything about it is simple.

Did the lower kit come with a jig, or did you get one separately?
[Reply]

Did you get a 80% lower or a stripped lower?

Do yourself a favor and get a small gunsmith kit that has rollpin punches. It makes the lower build way easier.

I've always been curious about the 80 percent stuff and registration. Do people register? do you make your own serial number? 6969420fkdafed?
[Reply]

To the best of my knowledge, the 80% lower is FFL-free, and basically no different than buying an upper or anything else online.
[Reply]

Arent you supposed to register it when its complete? if not im building a house and filling the studs with 80% guns. jk. or am I?

My condolences on the upcoming accident you are going to have where your canoe tips and all your guns go to the bottom of a deep lake.

Someone please explain to me why so many people make these Frankenstein AR’s?

I know they’re all supposed to be made to the same specs, but isn’t there a chance you’re gonna get parts that are off each other by just a hair when using 3-4 different makers?

Pretty sure I’d just want one machined by the same maker to ensure uniformity in such a finicky weapon

Paper weights made for personal use do not require numbers, unless you live in a paper weight hating state.

There's a reason they sell 80s 10 at a time. :-)
