The LSS-22 chassis system for .22LR caliber rifles is lightweight and compact, and adopts the same footprint as the LSS.

The Hs3 chassis itself is only 2.47lb / 1.4kg and was designed based on customer feedback who wanted longer fore ends (3" longer than our LSS), and use fixed rifle stocks (as compared to our LSS chassis which was designed for compact use with collapsible stocks). **Send me an email for current discount pricing.

The HS3 drop-in chassis serves as a base to which the operator can add tactical components according to the desired functionality. The stock is manufactured out of aluminum, hard anodized to milspec type III, and has durable Polymer side panels which can be ordered in black or Flat Dark Earth (FDE).

The HS3 chassis uses AICS style magazine in .223 and .308 caliber for short action systems, and 300WM, 30.06 or .338LM for long action systems. **Note** that the magazine well for Long Action has the 3.715 length, and therefore you need AICS magazine in 3.715.

The HS3 chassis supports installation of bolt on MIL-STN-1913 accessory mounting rails on the bottom and sides of the fore-end. For the sides you will need MDT's specific HS3 Chassis rails. The mounting holes are spaced for Magpul style L5 (11 slots) and L3 (7 slots) rails (1.600” / 3.200”).
