Hey, looks like I am going to come back to armalite, and in looking at there NM upper, it looks to be a great deal. How are they preforming for you guys? How's the weight?

Sold my custom ar10, then built up a Noveske MaTen , then traded it, think I am going to go with a a2 lower and the NM upper and call it a day. Optic will probably be a 2.5-10x nightforce

Mine runs pretty well (perfectly).

I am only getting 1.5" @ 100 w/168/FGMM out of it though. Can't decide if its me or the rifle..probably a little of both.

It's heavy, no doubt.

Probably the best deal going with a rail, heavy barrel and threaded end. I am happy with it.

hmmm, have you tried and 155grain or 175grain match stuff, any handloads?

I love mine, I bought it earlier this year when I completed my build. Its not too heavy, I run an Osprey scope, I actually have it on a collapsible carbine stock, I've had no trouble with it. I only put a hundred rounds through it and I was shooting clover leafs after I sighted it in. I plan on eventually sighting in at 200 and go from there.

Just got my upper on Monday and hit the range yesterday. So far only 20rds but it is MOA on my first outting. I was trying some reloads using 168gr Nosler CCs over 42.5gr Varget. I like it a lot. I know it's not a precision bolt but still is very nice. It was my first time with a Geissele two-stage trigger too.. so getting used to it. I heard everyone say how heavy it is.. but honestly I didn't think it was bad. I couldn't hold it off-hand for more than a mag consistantly but I have a PRS stock to give it better balance than a collapsable. To me it's a bench upper.. and it's not an AR15. I debated getting the NM upper or doing a build with a Noveske barrel.. I'm happy with the NM upper so far. have another 130rds of test loads to get through in the next week (more 168's, 175's and 190's. Finally nice weather round here.

When I had a factory NM upper, it would shoot the 175's under 1 MOA on demand, basically the M118LR copy. But it did not like 168's at all, and really neither do I in particular, just found that the 175 will do better in a wider area of rifles and ranges. The 190 Sierra also shot extremely well from the Armalite upper.

I ended up piecing together a krieger barrelled NM upper on my own, and it has an Obermeyer chamber, that is set up to run 175-190's at mag length. The two are the same dimentionally at the nose. It will keep them in 1/2 MOA. It is a 1-11 twist.

I have a NM A2, one of the first built.

It is the most accurate 308 "battle rifles" I have shot. It only has irons but will shoot circles around most guns.

I really cant see anyone not being pleased to go the NM route

Thanks for the info.

My buddy just picked one up at Camp Perry during the week of fun.
We were just talking about how to get some 178's to go 2600fps with a 20" barrel for 1,000 shooting. This is going to be a fun time experimenting.
