Ok before I get started I will state that I've not fired this rifle since putting it in a. Tight gi stock. I've noticed that the oprod guide has a bit of side to side wiggle to it, but not front to back. As in it pivots on the barrel. Is this something I should go ahead and correct before begin accuracy testing? Rifle is norinco m14s w/ original barrel/oprod/guide/gas system. If so how should I correct this? Thanks for any and all suggestions! Oh and merry christmas!
