Hoppe's® No.9 Synthetic Blend Modern Firearm Gun Bore Cleaner 5oz, 904GP.

Product does a good job of cleaning your firearm and making it look brand new like you just pulled it out of the box. Will always recommend to anyone.

Smell not as strong as regular hopps. Seems to take a little longer. Don't have to worry about it staining polymer stocks. Does good job cleaning bore and chamber. Does pretty good on removing copper

Works easy just like it should. Not a bad price for the amount you get. Smells terrible but then all fun oil does

Ease of use and always works for my guns this is only brand I use on my stuff.smell not bad at all easy applicator

Easily cleans rifle bores, making short work of carbon and copper build ups. Cleans quicker than the non synthetic blends, and leaves the bore with a mirror finish. 10/10 would/will buy again.

I hadn't been shooting for a number of years. Now I am back in the game. Hoppe's has always been my go to brand for cleaning supplies. Today's chemistry has come a long way. I still have some Hoppe's No 9 "Traditional" but now is just a keep sake.

It makes cleaning a lot easier

It does the job without smelling like cancer.

Being a synthetic, i think this does a better job of cleaning out a barrel then the older #9. Improvements are always being made, and i always like to try out new products. I still like the #9 and will continue using it, but will trade off with the new synthetic product and see what one gives the best results after time.

Product works well. Strong smell from bottle when purchased -- not sure if the lid was fully sealed. Once I transferred to an new applicator bottle, smell dissipated.
