I have the above 223 CZ 527 Carbine and am having trouble seating a Lucas Bore Guide. I have placed a drop of gun oil on the O ring to soften it up but the bore guide still will not seat. I am using medium pressure and turning the bore guide to the right when I try to seat it. The bore guide is clearly labeled as 223 CZ 527 but makes no mention of the model which in this case is s Carbine. Any help will be appreciated.
