• Our bushings will be slightly longer than the factory size to prevent bushing bounce which can damage the bushing. This is due to the factory's bushing being of one size fit's all which is not correct. We have found that after measuring the hole depth in hundreds of factory barrels the depths of the hole is inconsistent from barrel to barrel. Our adjusted size is a better overall length so you will not have to trim them 99% of the time.
• THE LENGTHS DO NOT NEED TO BE TRIMMED FOR THE FACTORY GAS BLOCKS!
