Łoże LSS - długi zamek

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.

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 110, 111, 112, 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.

Important Note: The Ruger chassis are a brand new product for us, and we know there are some variations between different rifles. the chassis may require some modifications, in particlular with the Predator and Precision models.  We do provide $50 refunds or $50 in product value to customers that provide detailed feedback.

If you prefer using a fixed rifle stock, take a look at our LSS-XL chassis.
