Hey Ryan. That gun was worked on by Rifle Dynamics (Jim Fuller and his crew). I believe that on the SLR-107UR, they remove a little donut restrictor that Arsenal puts in the gas port for the 16" barrel configuration. Contact Rifle Dynamics for further details. Thanks and Gig 'Em!

Hi Phil,

I noticed you have a an SLR 107 sbr and was wondering what you did for the gas system, or if it runs reliably without modification.
I think I saw a post about you being in CS? Is that still the case?
