Officially the Custom shop was closed to outside guns of any kind (ie non custom from the beginning) to catch up on workload. They have since opened up with about 20 or so options. Now even their custom guns are package deals, no modifications to those packages at all.
Unofficially, SA I think might be run by retards.
Ive had 3 guns worked over by them, they were fast, reasonably price and did damn good work.
