Breakthrough Clean Technologies Aluminum Universal Bore Guide - Rifle Cleaning Accessory - Fits Bore Sizes from .17 - .416

It’s a nice product but it doesn’t fit in my 17 hmr or my 22LR rifles. I use it in my AR’s.

As advertised. Fast shipping.

Works good

A big disappointment! The main tube is too short which places the solvent port right under the scope and makes it difficult to access. The threaded collar is so thin that it is almost impossible to attach the bolt. I have returned this item for a refund.

It works but I still question the actual need for this. It seams I could do the job on most of my "TOOLS" without it.

It's alright

works as it is intended

Cheap piece of junk. Bolt handle keeps falling out because there is only one or two threads that hold it in place and they stripped on the first use. The bore guides aren’t tapped right and are hard to get threaded on without cross threading them. Definitely worth spending a little more money and getting a better quality one.
