    i have a small right angle pick that may work. if there is no crud in the ports it will be a miracle. the amount of lead chunks in the gas tube was unbelievable. still makes me think if the ports are open enough to pass the chunks, i may not have to worry about it being undergassed.

    HRM... I wonder if the gas ports on that thing were shaving lead off of the buckshot and slugs, and the debris was being introduced into the gas chamber area. That would explain the debris. Or could just be the guy cross-threaded the plug I suppose. Or manufacturing/assembly defect that went through QC anyway.

    It does go back on OK, right?

    once i got the plug started then it turned freely. i may have taken 3 turns to get past the crud but after that it was smooth. but my god it was dirty and full of crud. i have it my welders shop right now getting the sights tigged. i do not trust my welding skill, especially with a wire fed on a very sensitive part of the gun. as soon as i get it back, i am going to take off the side rail and start fitting my underfolder trunnion.

    hcp, how necessary is the pg reinforcement plate when doing a underfolder.

    You said it's an S20, right? If the receiver is the same as a S12 you won't need it.

    What what was the outcome? you know the comment about the gas ports being opened up too much makes sense. Maybe the person opened them up then tried to restrict the over gassing by turning the thing down as far as it would go.

    wow i fell asleep on my own post. it doesnt look like the gas block was removed by the p o. i think he cranked it down too far and never cleaned it. i am in the process of doing an underfolder and hk sites. hopefully i will get it back together this weekend. here's where i am so far







    got all the extra holes welded up mounted the folder trunnion and rough cut the receiver for the stock mechanism.
