Well, Steve did it again. Ran flawless from the start. AR details (won't be as long as most of yours because it's pretty simple at this point)
RRA lower with NM 2 stage trigger
Match carbine upper from ADCO
WOA reciever, bolt and carrier
1/8 Wilson SS barrel with Wylde chamber and FSB
DD 7.0 M4 rail
RRA detachable A2 carry handle
and olive drab sling I got with my Garand from the CMP a year ago
I figured what better way to break in a new AR than 80 rounds of XM193 I had laying around. So I loaded up 3 mags last night. Sanchez, Okay, and D&H.
I zerod it at 25 yards with the small aperture and I used the XM193 for my front sight tool, recommended by markm and someone else. After doing it, I'd say it's an acceptable way and I'm glad I didn't buy a tool for $6 plus shipping or whatever it is.
My impressions of the carbine gas system we're pleasant. I don't think the recoil was any more noticeable than my colt 20" AR. And Xm193 is probably the hottest ammo I've shot. And the recoil was not "brutal" in comparison like somebody mentioned. In fact, it didn't seem any different and if I'm remembering correctly, it felt even less than when I shot Hornady 75 grainers through the 20". I was just using irons and this is what I shot from the bench:
2 of those groups were with the small aperture and 1 was with the large. My goal is to learn how to shoot the large aperture fairly well, but I'm finding that difficult. The weird thing was when I was using the small aperture the target was more clear. When I used the large aperture at 50 yards, focusing on that small of a target was nearly impossible for me. The black got so blurred I could barely see it. But it wasn't like that with the small one. Weird. It may be different if you're shooting at a larger target but when I used the large aperture that dang target blurred really bad. I must be getting old.
In fact, it even seemed harder to focus on the front sight too with the large ap. Anyone ever have this problem? Well enough about that.
This thing shot nice. No jams, failures of any kind and the brass all went in a similar spot. I'm going to put a scope on it to test some ammo tomorrow and I'm sure I'll be happy. Steve builds really nice uppers, which alot of you already know that. Oh, and that 2 stage NM trigger is very, very, very nice. It feels like half the weight of the old colt single stage.
