I have never used a bore guide to clean my rifles, but have decided it's time to start. I home made one makeshift to clean up my 700 sporter in .204 today, but it isn't ideal. I want to get a good one that fits snug front and rear for my rifles, one a Remington 700 in .204 and two more Kimber 84M actions in .204 and .223. Probly lots of good options but love to hear what folks like and why.
