M14/M1A CASM (Photos shown are of the CASM GEN II in aluminum (steel mount photos are pending)).

     The M14/M1A CASM® scope mount was designed in part by an ex-Canadian military officer and a professional gun smith with more than twenty years experience tuning and modifying hundreds of M14 and M1A rifles. Together, we've created a mount that is secure under recoil and will last a lifetime. The CASM® mount is CNC precision machined using 4140 HTSR steel and is Black Oxide coated. It includes a proprietary four point mounting system with 1/4" allen head screws and allen head lock screws to hold adjustments.

     This mount replaces the rear sight, and uses the much larger, sturdier and more reliable mounting area inside the rear sight pocket, and the solid rear sight ears, rather than using the more common, much smaller stripper clip guide. See our document entitled Engineering and Design Considerations for further review.

(These two photos show the CASM® Gen. "I" mount. Shipping mounts are Gen. II, steel version).

     Notably, there are no left side mounting legs required on the scope mount. It is designed to interface with M14 railed hand-guards, which pre-empt the use of the left side bolt hole mounting point. The Picatinny rail mounting extends from the front of the receiver all the way back behind the rear sight location. Detailed Installation Instructions can be viewed via the latter link.

     The M14/M1A CASM® scope mount is high enough to avoid the trapped cartridge case jams found with lower designs and the bolt is easily removed for cleaning without removing the mount. The CASM® ships pre-set for slight angle down at the front for optimum scope adjustment at long ranges.

     The M14/M1A CASM® scope mount is a solid, sturdy, and secure mount for your M14 rifle.

M14/M1A CASM®
"One of the things I noticed immediately was a definite reduction of the size of my groups. I was using surplus M118 ball, and I have only been able to shoot .75in groups at 100yards. I just thought this was the limitation of my stock NM rifle. The standard removable 3 point mount was replaced with your mount and I was able to immediately put several of the bullets into the same holes, with no more than a .50in between the fliers. Lets just say I am impressed. Thank you for making this mount." -James H., M14/M1A CASM® Owner

"I all but gave up on finding a mount for my rifle. I have been through three in the past...and they were all just horrible. The build quality, fit, and design elements [of the M14/M1A CASM®] are outstanding. The instructions were simple and I followed them to the letter without any hitches. Now I know why you don’t have to build it out of steel. Your mount is SOLID. I could use it as a carrying handle and wouldn’t worry about a thing. " -Van J., M14/M1A CASM® Owner, USN Vet
