Scottsdale, AZ -(AmmoLand.com)- Sonoran Desert Institute (SDI) is proud to announce that a complete AR-15 rifle build is now available in the popular 300 AAC Blackout, 7.62 x 35mm, caliber as part of its AR-15 Advanced Armorer Course.

SDI, an industry leader in providing accredited and accelerated distance learning, offers the AR-15 Advanced Armorer Course as part of its Associate of Science in Firearms Technology Degree or Advanced Gunsmithing programs, or as a stand-alone option.

“We've very excited to offer our AR-15 complete build in this highly popular cartridge,” says Zeke Stout, head chair of the SDI School of Firearms Technology. “The 300 BLK is a heavier bullet with great ballistics, and is already on the shelves of most major stores in the AR-15 platform. It’s really ideal for our students. Plus, since the barrel, crush washer and muzzle device are the only differences between the 300 BLK and standard AR-15s, students can still use their favorite accessories.”

The supersonic 300 AAC Blackout cartridge was designed to closely match the ballistics of 7.62 x 39 ammunition with a minimal number of non-interchange parts compared to a 5.56 NATO AR-15. To decrease the feeding issues that occurred with 7.62 x 39 ammunition on the AR-15 platform, the cartridge case was derived from the U.S. Military 5.56 NATO case and will work with standard AR-15 magazines while retaining their original ammunition capacity.

Stout explains that the only change that will be made to SDI’s very popular 5.56 AR-15 build will be the barrels, which will be 16-inches long and manufactured from 4140 steel with chrome lining on the inside to increase durability. The 1/7 twist rate is designed to work with all bullet weights in the caliber and the barrel thread for the muzzle device is 5/8 x 24.

The AR-15 Advanced Armorer Course presents a comprehensive overview of AR-15-style firearms, including history, development, and practical applications of AR-15-style firearms. Lessons include parts and functions, ammunition, trouble shooting, maintenance and repair. Also presented are sight options, considerations for building or buying your AR-15-style firearm, customizing the AR-15 with coatings and accessories, and a step-by-step lab for building a complete AR-15. This is a five credit hour course.
