SI-D has made a BCG that is drop in ready. The SI-D BCG was designed and tested for crucial weight to performance ratios. Reducing too much weight may cause integrity issues, while adding weight decreases overall rifle performance. SI-D has also tightened its tolerances in key areas for ultimate reliability and longevity purposes. Finally, a great deal of engineering methodology has gone into SI-D’s manufacturing process that allows consistency on a part that must perform every time. Key dimensions are continuously inspected, including Magnetic Inspection on the carrier and bolt.
