Failure to reach battery on ar15 .223/5.56 o ring - Pro-Shot Bore Guides .300 Blackout AR Platform Gun Cleaning Kit

Failure to reach ar15 .223/5.56 battery with o ring. Not sure how many stars as it could be operator error. I don't want to remove the o ring. All 1 inch patches pass with no failures, as the bore guide was designed to function with the o ring, but with a slight hesitation, but passed ok . The 1 1/4 inch patches with enough force on the bore guide that should reach battery, hangs up in the gap with great difficulties to remove the stuck patches .
