DETAILS

LSS V-shaped beddingCut view of chassis showing flat spots where the action touches the chassis.

Our LSS chassis system was designed to be as compact as possible. The V-shaped bedding and free floated fore-end improve accuracy and ergonomics. The fore-end allows for barrel contours up to 1" in diameter. The graphic on the right shows the 2 flat spots (V-block) where the action sits. The area below the action remains rounded for ultimate strength.

The chassis system is manufactured out of billet 6061-T6 aluminum, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).

To keep this chassis system compact, it was designed for collapsible AR-15 buttstocks, however fixed buttstocks can mounted with the use of a fixed stock adapter.
Alternatively, our LSS-XL chassis has a 3" longer fore-end has was designed to accept fixed buttstocks without the use of the adapter.

Recoil lug area allows for thicker lugs.

MOUNTING AND COMPATIBLE ACCESSORIES

The LSS chassis is designed to accept any AR-15 butt-stock and pistol grip (purchased separately), offering the option to customize from the wide variety of  Accessories available on the market.

The LSS chassis uses AICS style external box style magazines in .223 and .308 caliber for Short Action and .300WM or .338LM AICS style magazines for Long Action rifles, and supports installation of bolt on MIL-STN-1913 accessory mounting rails. Mounting holes are spaced for Magpul style L5 (11 slots) and L3 (7 slots) rails (1.600” / 3.200”) to be used on the bottom of the fore end up to 6.5" in length.

Note: Long action magazines come in 3 different lengths: 3.715", 3.775" an 8.050". Our chassis use 3.715 length magazines.

SPECIFICATIONS

For rifles with longer barrels to be used for long range (past 900 meters) we recommend our TAC21 or our HS3 Chassis systems.

WHAT YOU GET, AND WHAT YOU NEED

The LSS chassis system comes as a 1-piece chassis, with all required mounting hardware included. This includes new action screws, and a screw for the pistol grip.

To complete this chassis on your rifle, the additional items you need to purchase are:

  • Any AR-15 buttstock. For fixed buttstocks you will need the fixed stock adapter, or consider using our LSS-XL chassis.
  • A buffer tube for your buttstock. (Both milspec and commercial work on our chassis)
  • An AR-15 Pistol Grip. Ideally without a beavertail, or use a soft (bendable) beavertail.
  • At least one magazine

If you prefer a longer fore-end, please also see our LSS-XL chassis System or our HS3 Chassis System.

IMPORTANT NOTES

Howa 1500 / Weatherby Vanguard actions
This is the only action that we manufacture a chassis for, that has a flat bottom action. For this reason only our Polymer magazines will work. The fitting may need to be modified slightly for proper feeding.
For .223 models the bolt stop may be too long. This can easily be modified.

Savage models 10/110 11/111 12/112 16/116
For rifles with the bolt release at the bottom, the bolt release can be engaged through the side of the chassis, using a pin or tool. (Not included)

Tikka T3 - Long Calibers
Only our Metal 3.56 magazine will fit with the chassis for this action and needs to be purchased separately.

Savage Axis
The original recoil lug that comes with the rifle is required for installation into the chassis.
