What is this part?

[Dantes Inferno]

Was in the cleaning kit from a cz858. Looks like a muzzle device but I can figure out how it would attach.

Muzzle brake attached buy a cross pin, probably used on the SKS

Its a cheap SKS pin on brake. Highly ineffective. See how far you can throw it in any clear direction.

id disagree with that ^ i had one of these on my SKS for years! it totally reduced the muzzle jump and didnt seem to effect the accuracy. Good brake by my opinion.

Thanks, do you guys by any chance supply longer pins, or is it generic hardware store type deal?
