A while back while at my local Wal-Mart, I found they had e different makes on the AR-15 set up, actually the M-4. I was able to handle and fondle them and really liked the Sig-Sauer M-400 enhance version out of the three. They were a Colt and DPMS as well. I bought the Sig-Sauer then and there. Felt great and had a Mag-Pul forend, Buttstock, 16 inche barrel, flat top receiver, no carrying handle, came with a really nice soft carrying case with shoulder straps and extra storage compartments. Found the case sells normally $95.00 which was included. Also one Mag-Pul 30 Round magazine. 917 plus tax out the door. I liked the way it threw up to my shoulder, weighs in around 6 and 1/2 pounds. Adjustable stock with the ability to add a sling in several configurations, also a nice feature on the Sig was two spots at the rear of the receiver allow the use of quick disconnet swivels for mounting a single point sling, or you can put a two point sling using the forend position. Do I like it,yes big time. I really like the Mag-Pul furniture. Flip up rear sight, standard AR-15 front sight. used a riser block to mount a scope. Great trigger about 6 pounds, break nicely. There was a write up in the American Rifleman about this model, but it had a more conventional forend (tubular) which I didn't care for. If you get a chance check out Sig's website. May help you figure what you would like to have such a model you are wanting to build. Take care.

with 16" light barrel, put on MagPul guards and an AimPoint H-1 on a riser. I already had complete lowers. No BUS sights yet. I've been shooting it with GI (some) and my reload ammo (lots) for a year now without any problem. Accuracy is more than adequate for 100 yd. Upper was $325 and AimPoint was $600 with mount. I have higher grade uppers for accuracy needs, this one was for the purposes your mentioned.

Just about everybody making a AR makes a collapsible stock, 16" barrel version with whatever weight barrel desired.

Personally, I'd look at Windham Weaponry (the original Bushmaster guys)

The only other upper version I'd consider over anything else is a SBR'd AR with a real M4 barrel.

The main weight savings will come from the barrel, there is very little to be saved elsewhere on the upper.

A polymer lower, like the Cav Arms (they are out of business and this lower is made by GWACS Armory in Tulsa now) will save you about a pound.

I'm building a lightweight AR with a GWACS lower and this barrel.

Planning to use a Bushnell TRS-25 red dot sight with plastic handguards to save weight.
