With the ever rising costs of .223/5.56mm ammunition there has been an opening in the industry for lower cost alternatives for training and target shooting. Many manufacturers have introduced .22 Long Rifle caliber upper receivers to the industry. One of, if not the finest conversion in the industry is offered by Tactical Solutions. The rifle shown in this video has been surprisingly reliable. The video shows consecutively firing 230 rounds without a single malfunction. It is a testament to the quality of Tactical Solutions. The rifle was fed by Black Dog Manufacturing magazines, which their reliability complimented the quality of the Tactical Solutions upper receiver. The ammunition was provided by Remington. The load is their popular Thunder Bolt.
