re: How many Ar15 owners?

Here. I just bought a Bushmaster ORC. Magpul MBUS sights. Saving up for Trijicon ACOG optics.

I have a DPMS Mod A-15 adjustable stock, 5.56cal w/removable carry handle.

Your sig quote. You ever watch that clip. A stream of blood squirts out that dudes head 5 or 6 feet. That was a Vietcong dude who had just killed the S Vietnamese colonels wife and children. Justice was quick in Vietnam.

I remember when that picture hit the papers, it was one of the major turning points of anti-war sentiments of the American people, along with the Pentagon Papers. Sad thing is, the photograph did not show the 35 bound and gagged people in the ditch that Lem had just murdered, most of them police wives and children. This was the picture the press wanted, just as many of the pictures that define a moment in history that becomes a turning point.

M16 A1
Colt SMG 9mm

Can't post pics from phn and fwiw I don't actually own them. Issued to me. The SMG is an armadillo killing machine

Present. Rock river arms upper and lower.

Present.

Currently have a M4 Build. Currently working on another that I have the upper built for already. It's a CMMG A3 upper, with a Bushmaster barrel, carbine gas system and standard iron sites. Thinking about getting an essential arms lower to complete it.

Impingement vs piston

I have impingement. If kept reasonably clean it is not an issue. If you are a person who seldom or never cleans your weapon, go with piston.

If impingement is kept reasonably clean, then piston is a solution to a non-existant problem. Keep in mind that the US military uses impingment system in very dirty and hostile environments and gets excellent service out of them.

Impingement pros

1) simpler - less parts
2) generally considered more accurate - less moving parts (probably splitting hairs here)
3) less expensive - less moving parts
4) lighter weight - less parts
5) very reliable if given reasonable care
6) very mature and tested system - all the bugs worked out

Piston Pros
1) more reliable if you seldom clean your weapon
2) runs a little cleaner and cooler

But a downside is that all piston system AR´s are not equal as this is not a milspec design. Some are poorly designed and prone to failure. It is not yet a mature system in the AR platform in all makes and models. But given a few more years it likely will be.

IMHO.

Original AR´s are impingement driven.

All AK´s are piston driven.

Thanks Jimbeaux, nicely laid out. Something I haven't really looked into much.

Did anyone go with a .30 cal upper? Which one?

As in .308? If that's what you mean you need a different lower.

If you mean a 7.62 x 39 I have two stripped lowers and I am thinking about doing one in 5.56 and the other in 7.62x39
