Building the Suomi just got easier!
I am now offering my Suomi FCG and striker system as drop in parts. You send your FCG for exchange - or if you wish I will convert and return your unit. The striker and recoil spring assembly is outright purchase.
Some minor fitting is required as each home modified Suomi is a bit different.
It is not yet BATF approved but it is in the process.
