This gives you the potential for all the benefits of the chassis concept as well as its drawbacks. Many of MDT’s products are of this variety. The other, more populated, end of the chassis spectrum consists of chassis where the aluminum core has been extended to become the entire stock. The only penalty you incur is a small amount of the extra weight typically associated with chassis systems. To whit, you get the benefit of a ridged aluminum interface for your action to get you good results without bedding and one you can therefore easily use with several different actions. This minimal use of the Chassis derives the minimum benefit from the concept while incurring only a minimal drawback. On the minimal end of the chassis concept, you have a Manners Mini-Chassis system which, basically, just substitutes a machined aluminum block for the customary aluminum pillars, bedding, and bottom metal in what is otherwise a composite stock. Chassis are basically ‘buy and bolt on’ affairs. This is particularly true when dealing with the well machined chassis and properly toleranced custom actions that are now rather common in our sport. Because of this, chassis don’t require any bedding and seem to benefit very little from it when people do bed them. What are Chassis and What Advantages Do They HaveĪ working definition of a precision rifle chassis is that it is a rifle stock system involving the attachment of the action to a ridged metal core structure. This year, their new XRS has a swappable grip system that is right up alley and is a good part of why I chose to review it. Last year, MDT added an AR-15 grip adjustable for LOP and with improved geometry for precision rifle shooting that I briefly mentioned in my SHOTShow 2019 report on their ACC stock. Recently, a few chassis systems have finally added adjustable or swappable grip systems more involved than just using an AR-15 grip attachment. The big advantage of aluminum chassis systems that led them to dominate 3-position is just how easy it is to add adjustability to them. The less external support, such as bags and bipods that you have, the more the fit of the human interface matters, and the primary solution to fit is adjustability. Both sports also involve using the rifles with less than optimal or no external support. Both sports are competitions and the drive to win generally overcomes the tendency towards inertia. During this development period, precision rifle stocks have somewhat recapped the development of 3-position smallbore rifle chassis I watched years ago with respect to their adjustability,and I think the recent popularity of PRS / NRL has really driven this trend. Now, chassis systems are probably more common than stocks and the number of makers defies my ability to keep track of them all. There was a time when the iconic AICS 2.0 was pretty much the only player, really brought the idea of a chassis to our industry, and, most importantly, gave us the AICS magazine standard. For a number of years, I have watched the development of precision rifle chassis. This year I wanted to take a look at a chassis in the same way. In addition to examining the specific brands and models of stock involved, much of the function of these reviews was to discuss what composite stock technology does best and why. These being the Grayboe Ridgeback and McMillan Game Warden. The last couple of years I have done a couple reviews of composite stocks.
