SKS Muzzle break

[mardig88]

Hi,
i am thinking about purchasing one of the sks muzzle breaks marstar is offering.
http://www.marstar.ca/ac-NcSTAR/Muzzle-Breaks.shtm
the 2 that they have in stock replace the front sight pin on most barrels
how is this done?
and would installing it alter the sights alignment?
plus from the 2 they have in stock, which one would you choose and why?

thanks in advance

Possibly. The lighter one, because it weighs less. Just make sure it is on tight.
