I let a gas trap get away

[RCS]

Jim, They have made non-firing gas trap front ends in Rahway NJ for years without a detailed set of photos it is nothing. Average restorted or correct as they say on CMP gas trap would run around $20,000 to $25,000 and that would be a later serial number. An original gas trap barrel is valued around $10,000 maybe more if early, an original numbered
SA SPG stock is over $3000 if you can find one. The solid buttplates by SA run in the $700 to $900 price range, s/n 1969 when original would have used the very early solid buttplate.
A nice set of springs and follower rod is around $4000 now.
I think $4300 is going to buy you a lot of fake repro parts
