Description
Dropping a Howa 1500 long action into the MDT XRS is one of those upgrades you feel the first time you shoulder it. The core is CNC machined from a full-length piece of 6061 aircraft-grade aluminum, then wrapped in high-strength textured polymer panels that insulate your hands from the cold metal and give you a positive grip in any weather. It's the kind of foundation that keeps everything rigid and repeatable, whether you're prone behind a bipod or working off a barricade.
What makes the XRS stand out is that it bridges two worlds. You get the silhouette and shoulder-up comfort of a classic hunting stock paired with the guts of a precision rifle chassis. For the Howa 1500 and Weatherby Vanguard long action, this version feeds from 3.715-inch AICS-pattern magazines through an ambidextrous latch that's quick and natural to run, so you can leave the old floorplate behind and gain faster reloads.
Dialing In the XRS for Your Build
Fit is where this chassis earns its keep. Length of pull starts at 13.25 inches and extends past 15 inches using the included spacers, and the quick-adjust cheek piece lets you set comb height to line up perfectly behind your scope. Both a vertical grip and an angled grip come in the box, so you can set the hand angle that suits your shooting style right out of the gate. The barrel channel floats freely and clears contours up to 1.25 inches in diameter, so heavier profiles have room to breathe.
Room to Grow on the Howa 1500 Chassis
The generous 12-inch forend is loaded with M-LOK slots, giving you plenty of real estate for a bipod, ARCA or Picatinny rail, barricade support, or weights to tune your balance. There's an integrated barricade stop and sling swivel studs on the buttstock and forend too. At roughly 3.9 pounds depending on the inlet, the XRS keeps things manageable for a hunting rig while still feeling planted at the bench. It's a smart platform for anyone wanting to turn a factory Howa into something that shoots and handles well above its price class.

Frequently Asked Questions
What magazines does the XRS chassis for the Howa 1500 long action use?
This long action version feeds from 3.715-inch AICS-pattern magazines. It uses an ambidextrous magazine latch that's easy to operate from either side. Magazines are not included, so you'll want to pick up the ones that match your cartridge.
Does the MDT XRS come with grips and length of pull spacers?
Yes. Both a vertical grip and an angled grip are included so you can choose the hand angle that fits you best. The length of pull spacer kit is also in the box, letting you adjust from 13.25 inches out past 15 inches.
Will the XRS free float my barrel and handle a heavier profile?
The chassis floats the barrel and accommodates contours up to 1.25 inches in diameter. That gives heavier barrel profiles plenty of clearance without contact. It's a good match for both sporter and heavier-barreled Howa 1500 long action rifles.
Can I mount a bipod and rails on the XRS forend?
Absolutely. The 12-inch forend is packed with M-LOK slots for mounting a bipod directly or adding ARCA and Picatinny rails. There's also an integrated barricade stop and sling swivel studs on the buttstock and forend.
