I just swapped my saiga front sight base for a 24mm threaded front sight base. I think the new base is Bulgarian. I have just one question regarding the plunger spring and cross pin assembly that is supposed to retain a brake. Basically the cross pin that retains the plunger and spring feels really loose and free to slide in and out fo the front sight base. I went shooting with it and it didn't back out like i thought it would. Should the end be flared or staked to keep it in the sight base? Thanks in advance.

I got one from CSS earlier in the week. It looks great and appears to be rock solid in design. I punched my barrel (didn't drill) and i used blue locktite. It doesn't move or rattle at all.

I think I may have threads also. Not to hijack the thread, but I'm interested in how exactly you take off the sleeve. I have a pipe cutter.

Thanks to all the good info on the site, I just completed my first conversion on a 5.45 rifle. I'm hoping that my barrel is already threaded (Serial # prefix H09) but in the event it is not, I'm willing to thread it. I was concerned, however about shooting corrosive ammo through a rifle that doesn't have the typical muzzle attachment detent found on most AKs. If I utilize the Saiga FSB, with a flash hider that is not readily removable am I asking for trouble when shooting surplus ammo??? I'm thinking all of the threads, nooks and crannies at the muzzle will be hard to clean without compl
