Lockhart Tactical is now offering a free little gift with every MDT order!
Chassis – The ESS retains our proven V-block bedding system to form a solid and reliable base for the rifle action.
The magazine well has been refined for easy insertion of the magazine, while reducing rattle and movement.
The tab style magazine release has been replaced with a semi-flush ambidextrous paddle that can easily be activated by a weak or strong hand.
The recoil lug mortise has been designed to accommodate most aftermarket recoil lugs and the trigger area will accommodate most aftermarket triggers.
A serrated barricade stop has been added to the front of the magazine well and a polymer fore-end grip at the balance point adds comfort.
The wide fore-grip area combined with the octagonal profiled for-end tube offers flexible options when shooting over bags or improvised rests.
Thumb shelves have been added to both side of the chassis for shooters who prefer an open grip.
The most significant change is the incorporation of the ESS specific butt-stock interface, rather than the traditional AR pattern interface. This allows us to place the pistol grip in optimum relation to the trigger, while still allowing the shooter to choose from the wide variety of AR pattern pistol grips which suit their preference.
Butt-Stock - The MDT ESS chassis comes with it's own butt-stock, similar to our Skeleton Rifle Stock.
It is fully adjustable including lateral adjustment for the butt-pad and the cheek rest. Cheek rest height and butt-pad length-of-pull are adjustable by thumb wheels.
A butt-stock with an integrated folder will be introduced soon as well as an M4 carbine buffer tube adapter by Fall 2017.
Fore-End - Fore-Ends are offered in 3 different lengths, 12", 15" and 18", can be ordered with a full rail, partial rail, or no rail with cut-outs to allow low scope mounting.
Each fore-end comes with M-Lok slots and QD flush cup mounts.
Action specific scope mounting rails which co-index with the fore-end rail are available as an accessory.
