This is the M9 tuned Armsan RS-S1 10 round 12G shotgun (branded Citadel RS-S1 in the US).
We've been on a mission to improve the Armsan RS-S1 magazine and teamed up with M9 Engineering to develop an improved upper profile and locking geometry for competition users.
These start life as a brand new OEM magazine and are then CNC machined for improved clearance and catch engagement.
- Improved lockup - goes in with a smooth click, no more whacking them in
- Drop free operation
- Tough polymer design
- Steel feed lips
- Strippable for cleaning
There is good chance it will also work in VEPR-12 and Saiga-12 shotguns with magazine wells. If you have a VEPR or Saiga you would like to try one in please contact us.
