M1-S: M14/M1A Improved Modstock System
(3 customer reviews)


While our original M14/M1A Stock System has been the essential upgrade to the Springfield SOCOM platform, we saw huge areas of improvement. The stock system is now formed with VLTOR’s proprietary mold and is manufactured with a proprietary carbon fiber composite. This makes the stock system stronger and lighter than ever before. The stock is adjustable for five lengths of pull and adjusts for elevation. In its lowest position the stock will allow for the use of iron sights or the stock can be raised up to 1.25″ higher for use with mounted optics. This stock system features an improved magwell relief that allows for easier operation of any M14/M1A magazine. The buttstock is slightly wider and longer at the toe than a regular M4 stock with a noticeable negative pitch, making transitions from the ready position feel more natural.

The VLTOR Improved Modstock chassis is made to military specifications. There is a large amount of variation in the commercial SAI receivers, including variation in the height of the rear heel in the receivers. It is possible that you may experience a minor heel gap with your commercial receiver. The proper way to fix this heel gap is to build up the back of the stock by way of bedding. For this reason, we offer a “raw” version of our Improved Modstock chassis that is uncoated and features a bare carbon composite surface. If you plan on bedding the chassis for accuracy purposes, or to guarantee a lack of heel gap, you may consider purchasing the “raw” variation of the chassis to expedite the bedding preparation process. After bedding the stock, you may coat the stock portion of the chassis in a coating of your choosing. **Please note** Any bedding or modification of the chassis will void your factory warranty. For additional information please email TechSupport@Vltor.com

The M1-S Stock system comes included with: carbon fiber composite fore end, pistol grip assembly, buttstock adapter, and VLTOR EMOD buttstock.

*The VLTOR CASV-14 handguard system and Vltor ModPod bipod set are sold separately*

  1. Kenneth

    To say that I’m less than ecstatic would be an understatement. I have been looking for a long time for a system that would work for me and my M1a. I install the stock in about 15 min and seeing I was at the range( I’m the range master) I put rounds down range. This is not my old M-14 from Nam or my AR-10. I loved it, it really makes a difference. This stock system in quality work . You get what you paid for and it is made right here in the good old USA. I now will order the mount that goes under the stock the QDM-14 to finish the system off.

    Just got this in the mail today. Absolutely worth it. Very well made, but what do you expect from a US business today? Definitely recommend for the M1A SOCOM rifle.

  3. docsporseen (verified owner)

    This stock system has been a great addition to my SOCOM 16. I’m able to keep the overall length short, but comfortable, for close quarters use. Much better than the original plastic stock this rifle comes with.
