    If I am correct most standard front sights are 4moa so at 100 yards with xm193 55gr. you should have a 4 inch group and at 50 yards it should be 2 inch. unless you use match ammo then you should be able to have a little tighter group.

    That is correct assuming if you take human error out of the equation.

    a couple years ago, I bought an expensive rifle from one of the mfg that is very popular on this site. i got 4-8" groups at 50 yards with it. no keyholing either. i was shocked. tried all sorts of different factory ammo. nothing worked except oddly, my 80g SMK handloads that i used for 600 yard line in HP would go into the same hole at 50 yards. obviously, they wouldn't feed from mag and wasn't acceptable solution so... I sent the rifle back. they were able to reproduce my results. they checked all the usual culprits and couldn't find anything wrong with the barrel. but they replaced it anyway, tested it and sent it back to me. shoots fine now, but remains a mystery. heck, i don't even know how it's physically possible to get an 8" spread at 50. you could do better with a pasta noodle.


    i figure i know plenty of 5 year olds who can keep better than 4" groups at 50 yards. it probably ain't shooter error. i wouldn't waste a lot of ammo trying to figure it out. get it rebarreled.

    Try different ammo. Something is not right. Keep us posted.

    Front sight worked its way loose. I think some of you missed that. It's the last post on the first page. Hopefully I'm good to go now.

    I have a Colt M4 with the MBUS rear sight. I shot a 2" group with some LC 5.56 tracer rounds. I'm a bit low and am waiting for another decent day to lower the front sight (standard iron front) and try again. I believe that I can get the grouping less than 2". I wish the rear sight had elevation adjustment. One day I'm sure I'll get some kind of an optic sight for it. For now, I'll just keep working with what I have.

    Why zero with tracers? Those things do strainge stuff. Trident has a video where on just makes a left turn in mid flight.
