Magpul Pro 700 Folding Rifle Chassis

The Magpul Pro 700 rifle chassis is a complete system designed to elevate your precision rifle shooting experience. Its exceptional adjustability, Magpul-level build quality, and user-friendly features make it ideal for competition shooters, long-range hunters, and anyone seeking a truly customizable and high-performance rifle platform. My Bergara B-14R came with a great chassis, but it didn’t offer quite the adjustability that I was looking for. So I bought the Magpul Pro 700. It’s a definite game-changer for shooters looking for a highly customizable and versatile platform. While I’ve got the one for Remington 700 short action rifles (and clones) they make a Rem 700 long action version as well. This is a very comprehensive solution offering uncompromising performance right out of the box.

Magpul Pro 700 Folding chassis specs:

First, I need to point out that on their site, Magpul refers to it as both a stock and a chassis. These aren’t quite interchangeable terms, and I’m sticking with chassis, based on features and construction. Here are some numbers for the model I’m currently using (MAG802). Overall length is 32.7″ to 34.6″, depending on length of pull setting. It’s a mere 23.5″ when folded. At its widest, it’s 1.86″ across. And the weight with nothing attached is 5.4 pounds. My barreled action is 7.8 pounds. Throw in a scope with rings for another two pounds, and this is definitely not a lightweight rifle.

It’s got Magpul design and durability inside and out:

  • A solid foundation: The Pro 700 is built on a Type III hard anodized machined 6061-T6 billet aluminum frame. This ensures exceptional durability and rigidity.
  • Ambidextrous design: Southpaws are not left out. The Pro 700 is designed to accommodate both right and wrong-handed users with a reversible cheek riser, bolt cut-out plate, and QD sling swivel mounts. One chassis, either configuration.
  • Weatherproof and comfortable: Its combination of a machined aluminum skeleton and Magpul polymer body covers is nearly impervious to damage while offering improved ergonomics.

Twice now, I’ve bought another brand’s aluminum chassis, yet ended up swapping for a Magpul. I get all the rigidity, without worrying about dings and scratches at the range, or in the safe. And after building a custom lefty rifle for a friend, I have a huge appreciation for what Magpul has done with the Pro 700. It’s effortlessly simple to swap this chassis for left-handed use, should you have a left-handed action. The polymer over aluminum should hold up better than a full aluminum chassis over time as well.

Tailored to the shooter:

  • Multiple adjustment points: Easily fine-tune the fit with a wide range of adjustments for length of pull (LOP), comb height, butt pad position, and cheek riser fore/aft too.
  • Folding or fixed stock options: I chose the folding stock for enhanced portability, but a fixed stock is also available if that floats your boat.
  • Two grips to choose from: The Magpul Pro 700 comes with two grip options. They have different forward sweeps to match hand size and shooting preferences. The grip itself also has some fore/aft adjustment.

LOP can be varied from 13.25″ to 15.125″ on the fly, without tools. The butt pad itself can be adjusted up 1.33 inches, or down .90 inches, and left or right 5 degrees either way. Like the LOP, comb height is set without tools, on the fly. Plus it can be locked down once in place with a secondary knob. Its cheek riser can be moved forward or back .375″ in either direction. And as mentioned, it can be reversed for wrong-handed shooters. Loosening the grip screw allows for .75″ of trigger reach adjustment too.

Ready for performance and easily upgraded:

  • AICS pattern magazine well built right in: This mag well provides smooth and reliable feeding with a variety of magazines. That includes Magpul PMAGs as well as aftermarket magazines.
  • M-LOK slots for days: Mount your accessories such as bipods, lights, and slings with the M-LOK slots at 3, 6, and 9 o’clock. Plus more under the buttstock.
  • Night vision ready: An optional inline mount allows you to seamlessly integrate night vision or thermal imaging devices.

My Bergara uses AICS-pattern magazines, and they slide right in and drop free with the ambi magazine release. I’ve had zero feeding issues with them. I previously had a Mapul M-LOK bipod, but swapped it for the Magpul Arca rail and a compatible bipod. Unlike some of Mapul’s lower-priced stocks, the Pro 700 includes three QD sockets. There’s one on either side of the buttstock, and one opposite the bolt slot.

The little details

All that’s required to switch to left-hand use is a few minutes with a single 1/8″ hex wrench. The stock’s hinge folds with the push of a recessed, top-mounted button and stays in place when folded. It’s not locked in place, making it quick to deploy, yet it remains rattle-free. While my factory bolt handle fits the cutout in the stock, it can be reversed to fold in the other direction. That’s accomplished with a 5/32″ hex wrench. Two grips are included. One has a 5-degree forward edge sweep with an enlarged palm swell and a 7-degree rear edge sweep. The other has more aggressive angles, with 8 degrees of forward sweep and a rear edge sweep of 20 degrees. Magpul also offers an adapter, in the unlikely event that someone buys the folder and decides they want it fixed instead.

Installation and adjustment of the Magpul Pro 700

If you’re building a rifle on this foundation, then you probably already know how easy the installation is. Magpul includes a pair of 1/4-28 x 1/2″ long socket head scrap screws. No idea where mine went, but a quick trip to Ace Hardware and I had a new set of stainless screws. Removed my Bergara from its stock, dropped it in the chassis, and snugged down the screws. From there, I tinkered with the grip to find the best position. With that sorted out, I got the rough LOP and comb height set. Sometimes I shoot from a bench, and sometimes prone, so I really value the ease of adjustment on the fly.

Attaching accessories

Lacking the need (or budget) for night vision, my accessories were much simpler. In addition to the M-LOK bipod, I added a small rail section for my Arca adapter. And on the buttstock, I added another small rail section for a monopod. I’m still experimenting to find what works best for my needs, so these accessories will more than likely change over time. For now, it’s working well whether prone or off a portable bench.

Overall impressions

I bought my Bergara B-14R with plans to possibly compete locally. And I liked the idea of a rimfire trainer, with an eye towards a .308 or 6.5 Creedmoor in the future. Neither of those is necessarily a justification for the expense of the Magpul Pro 700, but I have zero regrets. At $999.95, it’s still less expensive than some other chassis options. Yet it offers all the features I could ask for, along with its easy adjustability. And I don’t have to worry about it getting scratched and beat up.

From an accuracy standpoint, it’s hard to quantify an improvement. As far as ergonomics, it’s night and day. My rifle fits like it was made for me. And that has contributed to consistent performance, especially over longer shooting sessions. Even if I had no intention of competing, I wouldn’t hesitate to use this as the base for my build. To date, it’s met all my expectations, and then some. And Magpul has expanded the lineup to include a fixed version, Lite version, and Long Action versions too. They’re available in black, FDE, and olive drab green. If you are considering your own, you can find them on the Magpul website.

Questions? Comments? Do any of my readers use one? Would love to see your feedback.

*My rifle as pictured is the Bergara B-14R in .22 LR with a Timney Calvin Elite trigger, topped with a Vortex Venom 5-25×56 scope. It sits in the Magpul Pro 700 folding chassis with an MDT GRND POD bipod on the Magpul Arca rail and an Accu-Shot monopod out back. I like to tell myself it’s “budget-friendly”, as I pieced this setup together over time.
