About the S2AR Adapter:

We shaved some weight on the Generation 2 S2AR adapter to come in under 6 oz.! Its other features include a QD (quick detatch sling cup) on either side for carry and rapid deployment of your firearm. A rear modification so as to be compatible with the MAGPUL ASAP AR-15 end cap, as well as all other known end caps.

Telescoping stocks that can vary the length of pull are ideal for body armor, cold weather clothing, female officers etc. The use of the AR-15 grip without a buttstock can be utilized in breaching, C.Q.B., in vehicles and when maximum maneuverability is essential.

While our competitors claim, "CNC machined aircraft aluminum", in reality they cast their adapters like some sort of a toy, machining only the holes. note that the term "aircraft aluminium / aerospace aluminium" usually refers to a 6xxx or 7xxx series billet alloy, not cast parts. I am fairly certain they do not cast aluminum parts for airframes.

We intricately machine the entire S2AR adapter from a solid billet of aluminum. Best of breed, simple, one piece... indestructible.

Will not fit the 887 model shotgun.

Will only fits Remington 1100/11-87 shotguns with ETA's RRS recoil system.
