Question: does this fit all caliber rifles? the bottom right opening looks so small how does a larger brush or jag fit in it?
Document: Now that I've used this for a few months, I can't believe I waited so long to buy it. Very high quality bore guide that locks tightly into the chamber and is held in place by the port door. Creates a safe and level entry point into the barrel without the potential of damaging the chamber or extension mouth with a brush tip or jag.
I bought this one because  of other feed backs on the green slicks one, that they do not fit or seal like it should. SO LET ME TELL YOU  this is the one you want to buy.
Love how it locks into place with the dust cover. Great fit and really well made. Get comments all the time at the range when cleaning my gun asking which bore guide it is and where to get one.
The Wheeler bore guide makes cleaning your AR a breeze. Just take a shop rag and place under the opening where you dispense cleaning agents and you will keep the lower from getting drips on it. The guide is well built and does just what it is suppose to do. It helps to have the rifle supported properly by the mag well.
I can't say I really like that as with repeated use it could cause scratching  the surface. A rod made out of some type of harder plastic would be better for this reason.The ID of the guide rod tube is larger than that of a barrel  so there is still some potential there for a less than perfect alignment when the rod leaves the guide and enters the barrel.
This one is the one you'll want and the way it is made will last forever. Anyone who sees this will be green with envy.
This is a nice quality item and fits my AR15 perfectly. I've only used it twice so far but i can tell it will outlast me. I've seen cheaper ones out there, but sometimes you get what you pay for. In my opinion, this was worth the price.
This certainly makes cleaning a bit easier and quicker for me.I got it mainly for the potential dammage to your barrel aspect when cleaning with a rod, and expected it to be another step that would add time. I was pleasantly surprised when it actually shaved off some time!
This bore guide is fantastic! It's the Cadillac of bore guides for the AR and you can feel it when you use it. It's hefty and strong and smooth and everything fits like a glove. I would highly recommend this product over any other AR-15 bore guide out there. Simply amazing.
Outstanding bore guide. It fits my AR-15 as though it were part of the rifle!. Very happy with this... Using a carbon fiber cleaning rod .from Tipton with this.
