How can a Bulgarian 74 barrel be used on a SAR2 trunnion? I believe the Bulgarian 74 barrel is 22mm at the trunnion and the SAR2 barrel is 23 mm. The only way I can think of is to sleeve the Bulgarian barrel. Is this safe?

Anyone ever sleeved a barrel?

never sleeved a barrel, but it sounds like a lot of work. Why don't you just install the bulgarian trunnion for your bulgy barrel? I believe they are the same width.
