Questions & Answers
Does the American flag model come with a buttstock and grip? Expert Answer

The US Flag OpticsPlanet Exclusive MDT LSS-XL Gen2 Chassis System will include a fixed stock interface, but does not include a buttstock. A pistol grip is not included, but any AR15 style grip will fit and function as intended.

The chassis has an integrated magazine as well.

The MDT chassis is a nice piece of kit. Be advised though, the picture associated with this item at the time of writing implies that you are buying the whole kit: forward stock, hand grip, and butt stock. But only the forward stock (called the chassi...

great chassis for distance shooting by gundoc, Verified Owner, January 17, 2025
Not light. This will add quite a bit of weight to your rifle. That helps with stability and recoil. My biggest complaint is that the photo shows the entire chassis with magazine, stock and grip which are not included. Had to order the MDT magazines t...

Great Chassis by Kyle Gron, Verified Owner, August 18, 2021
Looks good. Feels good. Easy installation. Lighter than expected. Perfect flush fit with the Remington 700 SA. MDT also has one of the best customer services around. Can’t go wrong with any of their products.

MDT Lss -XL G2 by Gary Porter, September 26, 2020
What can I say? Fit and finish are superb. Truly a drop in chassis with a high degree of workmanship. The Cerakote is flawless and everything fits tight. Definitely will buy MDT products for my next rifle.

Product Info for MDT LSS-XL Gen2 Chassis, Fixed Stock Interface

The original LSS-XL Gen2 Chassis, Fixed Stock Interface was designed as a variant of the highly popular MDT LSS chassis. The LSS chassis was designed for use with compact, short-barreled rifles. Many customers liked the LSS chassis, but wanted to use a fixed buttstock, and get their bipod out further forward.image

This prompted us to design the first-generation LSS-XL chassis, which has a forend extended by 3" and was designed to accept fixed rifle stocks without the need of using any adapters. One such buttstock that works great with this chassis is the TRYBE Defense Rifle Buttstock, made with high quality lightweight reinforced polymer and aluminum, and includes a buttstock and a set of cheek rests for ultimate comfort and functionality.

These Rifle Stocks are designed with V-shaped bedding surfaces, allowing you to drop your rifle right in without the need for additional bedding. The bottom profile of the V-block cutout has been kept round and close to the action without making contact, maintaining maximum strength. The MDT LSS-XL Gen2 Chassis, Fixed Stock Interface will free float barrels up to 1.350 diameter.

After the successful launch of our ESS chassis, requests started pouring in for the new features that had been introduced on the ESS chassis to be rolled out on our other chassis. In response, we have upgraded our LSS-XL chassis line with a Gen2 lineup that incorporates the new features.
