Just a basic conversion on a 19" threaded S-12.
I did use a RSA adjustable trigger, filed just enough to let the bolt hold open work.
I love the PK-AS-S I got from Tantal.
For now it just has black Duplicolor fogged over the welded up areas.
I'm going to put an AK-100 side folder or it.
Then I will coat it in flat black Norrells Molyresin.
The sling is a blue East German sling simmered in black Rit Dye solution.
Nice set up.
