I have an AR with a A2 front hand guard. I got an upper with a low profile gas tube stop so I can eventually put on a free float rail.
I was shooting it the other day trying to sight in my scope. (shooting from a table with sandbags) I was also sighting in my Mini 14 and noticed it was more consistent and accurate. groupings were much tighter.
i have read that the front end not being free float can make a difference.
My question is how much does it affect the accuracy/consistency?
I don't have the best scope on it. I am planing on replacing the scope and getting a FF rail.. which one do I do first?
thanks for the help,
What ammunition are you shooting 55 grain XM193 not the best to figure out accuracy with if that is what your using. Then if your mini 14 is producing tighter groups than your AR 15 then your AR or AR scope has serious problems. My pencil barrel Colt 6720 with standard plastic forearm and with its factory cheap chrome lined colt barrel will shoot 1/2 groups at 100 yards with Sierra 65 grain game kings over Varget from a good bench rest.
The worst AR out there with a reasonable barrel on it will out shoot most any box stock mini 14.
Replace your scope first and then try some factory loaded 77 grain matchkings.
If your groups don't get better than the mini 14 its likely a bad barrel on the AR so replace that before its a free float tube job.
