The Best Precision Rifle Chassis- Weight Comparison

Best Precision Rifle Chassis

Most of the modern chassis and stocks around nowadays are capable of performing at a very high level. Whether you get an XLR, MPA, MDT, Foundation, KRG, or Manners; they all have the same basic features. Arca compatibility, adjustable LOP, adjustable cheekpiece, and the ability to tune the weight. Weight has a huge impact on stability and the moment of the rifle under recoil. Most pros are running 25-pound rifles, so the amount of weight your stock or chassis can add is important.

XLR Envy Pro

The Envy Pro boasts a variety of great features that many chassis do not. For one, they have a very ridged forend and a arca rail extension that allows for the bipod to get farther out. This way you have the benefits of a long forend, without the flex that normally comes with it. The Envy Pro also has integrated thumbrests across the forend which mate with their weights perfectly. The XLR has a starting weight of 4 lb and can get up to 5.2 with the internal weights alone. It then reaches 6.5 with the buttstock weights, and 9 lb once the external M-LOK weights are added. These weights are awesome because they also add width to the forend, which adds stability. The Envy Pro can reach over 10.5 lb if things like the forend extension, NV bridge, and bag rider are added. If you are looking to purchase an Envy Pro, check out our competition package. It includes all of the weights and accessors to get up past 9 lb.

MDT ACC Elite

The MDT ACC Elite chassis is MDT’s flagship model. It boasts a whopping 19″ of forend with improved rigidity from their previous ACC Premier. The Elite has an amazing buttstock system that allows for quick removal and adjustments. Most of the adjustments use a push button system, that locks into place. For the few adjustments that require tools, there are Allen keys stored via a magnet under the cheekpiece. The ACC starts at 6.1 lb, and gets up to 12.75 lb with just the weights! The internal forend weight adds 2.5 lb and the external weights add 3.5 lb. They also offer a buttstock weight that can add 0.65 lb. With more accessories like the NV bridge and bag rider, the ACC Elite gets up to nearly 14 lb. If you are interested in an MDT ACC Elite, click here. It is important to note that the ACC Elite costs a ton to weigh down. It will run you $480 for the internal and external forend weights, and the buttstock weight.

MDT ACC Premiere

The MDT ACC Premiere predates the Elite but retains lots of the weight capability. It has a lower starting weight of 4.5 lb, but easily reaches over 11 lb with all of the weight we spoke about with the Elite. The ACC’s forend is not drilled and tapped, so there isn’t the capability for NV bridges, but MDT advertises a max weight of 13.5 lb. Again, it will run you nearly $500 to weigh this chassis down.

Zermatt Arms Matterhorn

The Matterhorn is the newest chassis on this list, and also the most expensive. It has a beautiful construction and build, and lots of space for weights. It also has cool features that allow for quick removal of the cheekpiece, which retains your adjustment setting. It has a starting weight of 6.5 lb and can reach nearly 12 pounds with all of the weights added. It could likely get even heavier if a different kind of M-LOK weight was used. Zermatt’s weights fit perfectly with the Matterhorn, but may not be the heaviest option. Using just the internal forend weights it weighs 7.8 lb, then 9.7 with the buttstock weights, and the forend weights bring it up to 11.9. If you are interested in the Matterhorn, click here.

Foundation Centurion

The Foundation Stocks are becoming very popular because of their “dead” feel, compared to a chassis. Although they may look primitive because of their wooden appearance, they are very adjustable and modular. The Centurion, which is their most popular model, has a starting weight of 6.1 lb with a full-length arca rail and Hawkins bottom metal. It has cutouts in the forend where 26 oz can be added for a combined weight of 7.25 lb. We spoke to John-Kyle, who is the founder of Foundations Stocks, and he said that they make a lighter model of the Centurion, which can get heavier. The light model has a cutout near the cheekpiece which can be filled with brass or lead to increase the weight even more. If you are looking for the heaviest possible Foundation Stock, then this next one may be for you.

Foundation Samson

The Foundation Samson retains all of the features in Foundations of other competitive stocks, but allows for more weight. It has brass inserts on the sides and a hefty brass arca rail which brings the weight up to 11.9 lb. The brass weights are even threaded so that more weight and accessories can be added.

Conclusion

Which of these is the best? Most of that comes down to preference. All of these stocks and chassis can get a rifle very heavy, but we wanted to compare their weights. Maybe this helped you decide on which chassis is right for you, or gave you some insight on the weights of different systems.
