Do your homework - Sylvan Arms AR15 & AR9 Gen 4 Folding Stock Adapter

Be careful if you are planning on using this SA folding adapter with the JP silent capture buffer spring! In  two places in the description is says it work's with it. "Compatible right out of the box" and "includes a bolt extension compatible with the JP silent capture spring" I found out neither of these are true at this time. They have encountered a manufacturing problem with the bolt extension and it is not available at this time. As for the adapter itself it looks really well made, I had seen some reviews about a gap when it was unfolded but saw nothing like that with the one I received. Looked to be very good quality but since it wouldn't match up with the JP silent buffer spring I had to send it back. Will keep checking with SA and hope they get the issue resolved. Probably would have given it five stars but was lied to twice so three stars. Hope this helps some of you.
