do a google search.
i used on my rifle with a brnd new barell, and fooling is almost reduced to minimum. i put through tube more then 500rounds, and i clened twice with coper mover.
before i did a chech to see how bad it was, and you will be surprised how well it works.
the ideea is: use one patch of gun juice, shot one round, and so on 10times.
then just use gunjuice to replace your gun oil.
for me it takes 3patches and 5min to clean the barell, and 20min to clean the muzzlebrake.
this solution works...
it makes your rifle shoot with 80-100fps fa ter, and increase your barell life alot.
makes all the moving parts, more smoth, less friction, less coper residue on barell.
