MDT LSS-XL GEN2 FIXED R700 SA BLK
MDT LSS-XL Gen2 Fixed, Remington 700 SA, Black
So you want real accuracy gains without buying a new rifle. This chassis gets you there. The MDT LSS-XL Gen2, fixed stock interface, built for the Remington 700 Short Action. Black Cerakote finish.
This is not a basic drop-in stock. Also, this is not a flexing plastic chassis. First, it’s CNC machined from a single block of 6061-T6 aluminum. Next, it uses MDT’s V-bedding system to free-float your barrel. Finally, it converts your bolt gun to run AICS-pattern detachable magazines.
Will this fit my MDT LSS-XL GEN2 FIXED R700 SA BLK?
Yes, if you run a MDT LSS-XL GEN2 FIXED R700 SA BLK So this chassis is built specifically for that action length. However, it won’t fit a Long Action 700 without the matching Long Action chassis. Therefore, confirm your action length before ordering. This is the right-hand, fixed-stock version, so check stock interface needs too.
Does this chassis actually improve accuracy?
It’s built to. The V-bedding system seats your action consistently, shot after shot. So you remove the variable of inconsistent bedding contact. Also, MDT cites accuracy gains up to 21% with this chassis design. First, that comes from consistent action-to-chassis contact. Next, it comes from the free-floated barrel, which avoids contact-related point of impact shifts.
What’s the fixed interface, and why pick it over carbine?
Fixed interface means you run a fixed AR-15 style buttstock, not a collapsible carbine stock. So this suits shooters who want a set length of pull and don’t need adjustability. However, if you want a collapsible stock option, MDT also sells a carbine interface version. Therefore, pick fixed if you know your ideal stock length already.
What magazines does this chassis use?
AICS-pattern external box magazines. So you get faster reloads and higher capacity than a typical internal magazine setup. Also, this MDT LSS-XL GEN2 FIXED R700 SA BLK accepts magazines up to 3.715 inches in length. Therefore, most standard AICS-pattern mags will work without modification.
Who is this chassis best for?
This fits precision shooters, hunters upgrading a factory stock, and competitors running PRS-style matches. So if you want a stiffer, more consistent platform for your Remington 700 “Short gun” , this chassis delivers that. Also good for anyone wanting AR-15 stock and grip compatibility on a bolt gun.
