US Army (2ID) M-14SE
Fig. 1. Smith Enterprise, Inc. US Army (2ID) issue M-14SE with standard Leupold Mark 4 3.5-10X40 LR/T M3 Telescopic Sight.

Our strategic intent with this project has been to offer current M-14 users a thoroughly reliable, proven and cost-effective modernization program as a compelling, cost-effective and fast track course of action for a modern 7.62mm NATO caliber Squad Designated Marksman (SDM). Our customers have proven in combat that the M14SE will fulfill this same tactical mission as a new production 7.62mm NATO SDM would be required to accomplish at one-third to one-half the price.

Precision rifle enthusiasts and official-end users have long been aware of Smith Enterprise’s established expertise in the area of the M-14 rifle. Since our incorporation in the early 1980s, we have successfully addressed all the documented shortcomings of the original M-14, M-21 and M-25 designs. To that end we have established a very successful business incorporating these product-improvements in customer-supplied M-14 rifles to exceed standards far beyond the original M-14 and M-21 design parameters, in all areas of functionality, accuracy and reliability.

During that time we have rebuilt numerous M-14s for various USG users, to include all branches of the US Armed Forces, the Department of the Interior and various law enforcement agencies. With the renaissance that the M-14 is now enjoying in the Armed Forces, it is no wonder that American military units now involved in the Global War or Terrorism have adopted many of our combat-proven M14 components. Additionally, we have also produced weapons based on our own billet bar stock M-14 standard, single-lugged and double-lugged match-grade receivers, which to this day have remained the industry standard.

Collectively, our modernization effort is known as the M-14SE “Crazy Horse” Semiautomatic Sniper System.
