Question 1

How much does the replaceable filters cost?

Accepted Answer

Mine came with several extra ones and I’ve not had to change it yet in over a year. If you email the company they will send you some. Last year they would do this at no charge.

And it’s a simple make your own out of 50 micron filter paper. That will end up costing about .01 each

Question 2

Does this fit a 300 Win. Mag?

Accepted Answer

Hello.  The RifleKuhl Stem will fit most long action receiver brands.  The Stem will be long enough to seal at the breech face or be slightly off the breech face.  If you have any other questions, please contact us at info@magnetospeed.com or call us at 512-284-8161 ext 1.

Question 3

how well does this work on suppressors?

Accepted Answer

It works well for the barrel.  It is built better that the cheaper alternatives.  Additionally it has a dust filter which is useful when shooting in the desert.  However, specifically cooling a can, it works as just as well as cooling the barrel since it is attached.  Not super fast but much quicker than without.  It is particularly beneficial during load development and shooting matches where the breaks between the strings of fire are short.  Nothing beats water but don't expect your can to last forever if you go the quenching route.

Question 4

Anyone figure out a way to use this with a muzzleloader (without pulling the breech plug)?

Accepted Answer

Hello. This was not designed for muzzle loaders.  It is designed for standard centerfire or rimfire breech loaded firearms.  The flange seal can seal breech/chamber faces from .22lr up to .338LM.   If you have any questions, please let me know.
