I have an LMT 16" upper that I am having accuracy problems with and need some help in trying to figure out what the issue is.
I bought it last year, but didn't have the opportunity to shoot it much until fairly recently, and most of it has been at relatively short range. I have taken several classes since Oct., but most all of the shooting has been 25 yards or less. The accuracy at short distances has been good enough that it didn't cause me much concern. Occasionaly when the distance was stretched to 25 to 50 yards, the groups started to open up, but I attributed it to poor shooting on my part.
This past weekend I had a class that did a little distance work, and this is when I began to question the rifle more than myself. We shot at about 100, 200, and a little over 300 yards. I was unable to get a consistant hit while everyone else was 'clanking steel...'. I was a little frustrated and a little embarassed, as I generally regarded myself as a better shot than this. With my Colt 6721 upper, I was able to consistantly shoot less than 2" groups with irons at 100 yards.
Yesterday I was able to go to a range and sit down and see what the upper was doing at 100 yards, and I was more than a little disappointed in the performance... I am just still not sure if its me or the rifle, and will have to wait until I get back up to Oregon and shoot it alongside my 6721 and compare the two side by side with the same optics.
Essentially the best I could do yesterday was a 5-6" group at 100 yards with either an Aimpoint or a TA31F. There was no real pattern to the shots, they were just randomly scattered around the point of aim. I was shooting this in a prone position with the rifle on a pack for a rest, using sound shooting priciples including trigger finger placement, smooth pull and consciously letting the trigger reset, as well as breathing and accurate sight placement. I was shooting Georgia Arms Canned Heat, and thinking it might be the ammo, switched to boxed Federal XM-193, with the results being the same for both. I checked my forend to see if it was loose (KAC RAS II), checked both mounts for the optics (both mounts from Larue) for tightness and could not come with anything that would indicate a problem.
Any further suggestions? What options might I have if the upper should be determined to demonstrate less than expected or acceptable accurcy? I was also under the impression that LMT used Mike Rock barrels, does anyone know if this is true?
Thanks!
