Questions & Answers
Would its gas block fit slim free floating handguard on Savage MSR-15 Recon? Thanks! Expert Answer

No, you would need a low profile gas block, which this kit does not include.

Product Info for Adams Arms MPSDADA AR-15 Gas Piston Kit 16"-18" Mid-Length .75" Diameter

The Adams Arms Piston System: A short stroke free floating piston system. Is Self-Cleaning. Carbon and gases are expelled forward, away from operator. Corrosive resistant coating processes. Harmonics are not transferred into the barrel. Adjustable gas settings for various applications. Doesn't vent directly to atmospheric pressure; this eliminates flash signature and super sonic crack which is optimal for night vision and suppresses fire. This system requires a carbine gas length (7.866" from barrel extension to shoulder) and a .750" gas seat. We recommend using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.image
