Łoże LSS-XL - krótki zamek

The LSS-XL chassis system is a variant of our highly popular LSS chassis. The LSS chassis was designed for compact use, short barrelled rifles. A large amount of customers really liked the LSS chassis, but wanted to use a fixed buttstock, and use it with longer barrel systems. 

This prompted us to design the LSS-XL chassis system which has a fore-end extended by 3" and is designed to accept fixed rifle stocks without the need of using any adapters. In addition the Lengt of Pull (LOP) is 1" shorter than the standard LSS, as fixed rifle stocks generally are longer than collapsible.

The chassis is designed with v-shaped bedding, allowing you to drop your rifle right in without the need for additional bedding. The bottom of the action housing has been kept round and close to the action without touching keeping maximum strength. The chassis also free floats barrels up to 1" in diameter at the muzzle end.

IMPORTANT NOTES:

Using our Skeleton Rifle Stock V3 - We do not recommend using our Skeleton Rifle Stock V3 on the LSS-XL. It will work on our LSS using the fixed stock adapter. But on the LSS-XL with a shorter Length of Pull the cheek riser will be in the way of the bolt. (it does work on some actions if the cheek riser is raised). But please check our Skeleton Rifle Stock Light, which was designed specifically for this chassis!

Please note important action specific information at the bottom of this page.

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. It will be a tight fit, and the magazine may need to be modified slightly for a good fit and proper feeding.
For .223 models the bolt stop may be too long. This can easily be modified.

Savage models 10, 11, 12, 16
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)

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

Winchester Model 70
Only compatible with MDT Polymer magazines.

DIMENSIONS
