ARMS #38L-S-EX Mod Gen II SWAN Sleeve Mod Gen II A.R.M.S. Riser w/ Rear Sight
The item is new and un-used and is sealed in the original packaging.
The SWAN® Sleeve provides a platform that is semi-permanent to the 5.56 cal M16 type weapons equipped with a flat top receiver. It raises the rail by 1/2″ while protecting the rifle dovetail rail.
When mounted, it gives the rifle a back-up rear flip up sight and makes the upper and handguard act as a monolithic system, perfect for mounting lasers and other items that you don't want to shift zero with.
This product integrates well with the ARMS 56 series of hand guard and #41 folding a frame gas blocks.
