Must have - Gunslick AR-15 Rifle Bore Guide

must have item for easy AR cleaning. well built milled billet aluminum fits perfectly in the upper for ease of cleaning. no more worries about beating up your chamber. also, brushes easily slide through bore guide(some other guides have too small of an opening and wire brushes wont fit)
Pros: solid construction and makes cleaning easier
Cons: none
