Magpul Pro 700 Rifle Chassis System

When Magpul announced the Remington 700 Hunter Stock I remember thinking to myself that it wouldn’t be long until we see a precision rifle chassis from them. I also remember thinking that a well designed priced right precision rifle chassis from Magpul could dominate the low to mid range rifle chassis market. Well I’m here to report the good news that Magpul has officially announced the “Magpul Pro 700” rifle chassis. Unfortunately though I’m more than a little surprised by the $1000 MSRP. That is three times the cost of the hunter stock and in my opinion about 1/3 higher than it should be because at that price shooters are at the price of a complete Savage Stealth or Ruger Precision Rifle. Those are great tack driver chassis based rifles for the cost of the Magpul Pro 700 chassis. Insult to injury the lack of an ARCA plate is a deal breaker for precision rifle crowd. Now with that said I’m a big believer in actually trying hardware first hand instead of relying on critical negative reviews of a product very few have seen or touched. Additionally Magpul still has time to address any perceived shortcomings pointed out by the community.

Magpul Pro 700 Rifle Chassis System Description

The Magpul Pro 700 Rifle Chassis System is an uncompromising, full featured precision rifle chassis for short action Remington® 700 actions and other Remington® 700 footprint actions. The Pro 700 combines innovative engineering, precision machining, Mil-Spec quality finishes, and an extensive list of purposeful design features with complete adjustability to provide demanding end users with the most comprehensive available precision rifle platform solution for true out of the box performance.

MDT LSS XL Chassis Details

The original LSS-XL chassis system was designed as a variant of our highly popular LSS chassis. The LSS chassis was designed for use with compact, short barrelled rifles. Many customers really liked the LSS chassis, but wanted to use a fixed buttstock, and get their bipod out further forward.

This prompted us to design the first-generation LSS-XL chassis system, which has a forend extended by 3″ and was designed to accept fixed rifle stocks without the need of using any adapters.

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

  • Bold, modern new look
  • Ambidextrous magazine release
  • Thumbrest above trigger guard
  • Larger barrel channel to accommodate barrels up to the diameter of the action
  • M-Lok pattern attachment slots on all 5 sides of the forend
  • Barricade-stop grooves ahead of mag-well
  • Side-relieved mag well to accommodate bulging magazines
  • Collapsible and fixed buttstock interface options

The chassis is 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 LSS-XL Gen2 chassis will free float barrels up to 1.350” diameter.

MDT LSS XL Gen2 Mounting and Compatible Accessories

The LSS-XL Gen2 chassis are designed to accept any AR-15 buttstock and pistol grip (purchased separately), offering the option to customize from the wide variety of  Accessories available on the market.

The LSS-XL Gen2 chassis accepts AICS-pattern external box magazines, and supports installation of M-Lok patterned accessories along the forend.

Note: Long action magazines come in 4 different lengths: 3.560”, 3.715″, 3.775″ and 3.850″. Unless otherwise specified, our long action chassis use 3.715 length magazines.

The chassis will accept recoil lugs up to .350″ (8.9mm) thick.

  • Increases accuracy by up to 21%
  • CNC Machined from 6061 Aluminum.

What you get, and what you need

To complete this chassis on your rifle, the additional items you need to purchase are:

  • Any AR-15 buttstock.

  • An AR-15 Pistol Grip.  For fixed interface chassis, a grip without a beavertail, or with a soft (bendable) beavertail must be used.
  • At least one magazine

Important Notes

Howa 1500 / Weatherby Vanguard actions

Only our polymer magazines will work in the short action rifles due to the flat bottom. The long action rifles will work with the metal 3.715″ magazines without fitting.

For .223 models the bolt stop prevents the bolt from moving back far enough to pick up the rounds.  This can easily be modified by removing the bolt stop and trimming the contact face.

Savage models 10/110 11/111 12/112 16/116

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 Long Action in 338 Lapua Magnum

Savage Long Action chassis systems all use 3.715″ AICS magazine wells. The BA in 338 Lapua Magnum uses 3.850″ magazines and have recently switched to a thicker recoil lug which will not fit our chassis. The ESS has been specifically designed around the current BA 110 in 338 Lapua Magnum.

Tikka T3 – Long Calibers

Only our Metal 3.560 magazine will fit with the chassis for this action and needs to be purchased separately.

Ruger American

The action screw is located directly above the magazine lever. This means that the magazine lever needs to be installed AFTER installing the action into the chassis. Detailed instructions are provided, and an installation video can be found here.

Ruger American in 223/5.56mm requires the use of a magazine with extended feed lips, such as this one: http://shopruger.com/556-NATO-10-Round-Magazine/productinfo/90458/.  This is to prevent the round from being released before entering the chamber.
Does not work with 300 Blackout

This chassis will also accept the Predator and Ranch versions. Please read the notes above regarding magazines for 223/5.56 rifles.

Dimensions shown are based on Remington 700 Short Action. *Skeleton Carbine Stock show below is the 9.75″ Version

BROWNELLS MDT BRN-1 M-LOK CHASSIS

To me this is an unexpected product offering from Brownells, a Brownells branded MDT LSS Chassis. Brownells used to be slow to respond to firearm market trends and in my opinion this bolt action chassis finally shows some forward thinking on Brownells part. For me as i have stated before I really like partnerships between my favorite companies and Modular Driven Technologies and Brownells are two of my favorites. lastly i think the Rams head logo is a cool touch given that’s exactly the types of beasts that might see action from this chassis.

There are currently 18 models to choose from including two for the Ruger American Rifle. Colors are Black or Flat Dark Earth aka FDE

SPORT-TACT CHASSIS SYSTEM

The Sport-Tact line of sporting tactical rifle chassis has been developed from Military requirements and the needs of long range hunting enthusiasts. The approach to the design of the chassis line was to keep the three major component groups completely modular (Butt-Stock, Center Section and For-End) to allow a mix and match scenario to satisfy any solicitation or sporting requirement.

The corner stone component of the sport-tact Chassis system is the dedicated center section in either short or long action. Currently we offer these for Remington and Savage based systems. Matched with current offerings of AM Products cartridge magazines.

Very Simply you can build your own chassis system by selecting the desired butt-stock, center section and fore-end from the option described before and shown to the right and select a finish of either Black Hard Coat or Gun Kote Flat Dark Earth or Sand.

In addition to the center section options for most of the major rifle receivers, many fore-end and butt-stock options are available. Butt-Stock options include a fixed butt-stock machined from 6061-T6 aircraft grade aluminum and a folding butt-stock with aluminum frame covered with a plastic skin for a soft and warm feel. Folding stock models are available with and without a butt-spike. Fore-End options include a short, open top rail section with a full length bot-tom rail and movable rail segments on the sides. Also available is the Accurate-Mag tactical fore-end with full length top rail on top and either integrated picatinny rails machined into the front portion of the fore-end on the sides and bottom or with a Modular Rail System running the entire length of the sides and bottom.

Masterpiece Arms MPA BA Chassis

August 21, 2017, As I update this post on the Masterpiece Arms MPA BA Chassis System it’s interesting to note that the MPA BA Chassis acceptance in the field has grown exponentially in the past two years. I think we need to get one in our hands soon.

The 5.2 pound Masterpiece Arms MPA BA Chassis take any AICS type magazines (Magazine not included). See related products for magazines for your chassis.

This unique chassis system provides a super precision platform for the Remington 700 Short and Long, Savage and Howa Short or Long Actions, Badger M2013, Mausingfield, Surgeon, Stillers, Surgeon and many others. New inlets are being added frequently.

Whether you’re increasing the accuracy capabilities of your existing action due to the V-Bedding System as well as adding tactical features to your rifle, or building a super precision rifle for long range competitions, the MPA BA Chassis will provide a world class chassis system sure to exceed your expectations. We also inlet for Tikka T3, Badger M2013, Surgeon 591SA & 1086 LA and others.

The V-Bedding system is also configured to allow the ability to glass bed the action and straight section of the barrel if desired.

The chassis is machined on our CNC Horizontal Machining Centers to exacting tolerances from 6061 aluminum. The MPA produced Buttstock includes an adjustable length of pull, recoil pad with height and cant adjustment, adjustable cheek riser and adjustable Monopod.

The monopod will lock into the vertical position, and has a quick height locating method with fine adjustment capabilities. When not in use, the Monopod tucks into the frame of the buttstock. There is a vertical position and also one at 45 degrees, used when you need that “in between” height of the buttstock of the rifle in acquiring the target.

Length of pull is between 13.75-14.75″ although this length can be modified by thinner or thicker recoil pads. Weight is 5.2 lbs.Coating is Ceramic (Cerakote) – all available in a variety of colors. The upper Night Vision bridge provides a seat for a picatinny rail. A matching rail is mounted to the bottom of the chassis – both giving the shooter plenty of rail space for a variety of enhancements.

On our chassis for the Stillers TAC338, this chassis will not have the barricade stop system nor will it have the option for the supplemental rail. These two features (barricade stop and supplemental rail) are features that are not normally used when shooting a 338 Lapua Cartridge.

The maximum barrel profile on our chassis, without modification to the barrel channel, is an M24 contour. If your barrel has a larger profile, please contact MPA to discuss. We can go up to a 1.250 straight profile, but need to know at the time of order.

For Savage Actions, our Chassis will accommodate both Top and Bottom Bolt Release configurations. Available for purchase from Brownells.

  • Machined from 6061 Aluminum
