Hi, I built a .22 AR and used an S/B Tactical side folding stock. Now, the charging handle interferes with the big button on the side folder spring. Anybody else have this problem and what did you do ?

I ran into the same issue. I ignored the part where it said it's not made for AR-15's. I though it was for the obvious reason that AR's need their buffer tubes cleared the whole way. Little did I know that it would block the charging handle. They could've designed it to work with AR-15 charging handles, but w/e.

Sold it and moved to the Hera SFU. Installed it with a downward tilt to clear my finger when pulling the charging handle.


Charging handle finger clearance with tilted SFU:


Knock of LAW folders are a good option. But I wanted use of a QD endplate, so I went with the Hera.

For those wondering, it's a 7" rail with 2x barrel extensions and a 3 lug mount on the end for use with an SilencerCo Octane 9 designated for .22's with braces (No baffle strikes .)
