How tight and/or loose is ok for the barrel extension to fit into the upper receiver? I have a barrel that is really tight fitting into a new noname upper receiver but it is a touch loose fitting into a new colt M4 upper receiver. When the nut is done up the barrel doesn't move but before the nut is tightened there is some wiggle room between the extension and the M4 receiver, there is not wiggle in the noname receiver and it is a bitch to get the barrel into and out of this receiver. Is either ok to use? Thanks for any input. |
