.22 Long Rifle CONVERSION FOR THE BLACK RIFLE PART 2 By Christopher R. Bartocci Without a doubt, the .22 Long Rifle caliber ammunition is the most popular in the industry. Rifles and handguns are made in every configuration possible making it a universal caliber. For the occasional plinker there is a gun and ammo combination and for the competitive shooter there is a rifle and ammunition combination as well. Hunters love the caliber for small game. All of the major U.S. ammunition manufacturers make multiple loads in this popular caliber. Ammunition is broken down into 4 categories for the most part. First is subsonic, which is normally 1,050 fps or less. This is good for use with suppressors as well as when noise is desired to be reduced. The second is standard velocity, which is normally around 1,150 fps. This is often target and match ammunition. The third is high velocity, which is usually around 1,280 fps. This is often for target and hunting ammunition. Also, this is preferred in semiautomatic firearms to reliably cycle the action. The fourth is hyper velocity, which is around 1,500 fps. This is normally a hunting load. Projectiles for the .22 Long Rifle are basically lead round nose or hollow point. Often they will be copper plated to keep the bore from leading. Some are truncated cone shaped such as the Remington Viper and Yellow Jacket. These truncated cone shaped projectiles often encounter feeding problems in semiautomatic firearms. There are specialty bullets as well is various subsonic loads. For instance, Federal Cartridge Company offers standard (Champion), subsonic (American Eagle), match (Gold Medal) and high velocity (Champion and Game Shok) hunting rounds. Remington offers a wide range of loads. In standard velocity they offer a .22 Target Load. In high velocity they offer the Cyclone, Thunderbolt and Game Load. In hyper velocity they offer the Viper and Yellow Jacket. CCI offer one of the largest selections of loads. In subsonic they offer the Subsonic HP and Quiet .22. CCI offers Standard Velocity with the STR VEL, Green Tag Match, Pistol Match and Select. High velocity offerings include SGB, Mini-Mag and AR Tactical. CCI offers hyper velocity rounds in the Stinger, Velocitor and SRG. Winchester offers a significant number of options as well with one in particular that is pertinent to this article. It is called their M22 load which is a 40 grain Black Copper Plated round nose projectile fired at 1,255 fps. This was specifically designed to burn cleaner in AR-type .22 Long Rifle rifles.

Above: Left to right: The original U.S. Government M261 conversion kit used by the U.S. military from the 1970s until the adoption of the M16A2. The second is the WMD “Little Beast.” This is a NiB-X coated conversion kit designed by Jonathan Arthur Ciener. It is an Atchisson-style drop in carrier. This particular conversion bolt is sold by CMMG and Stag Arms. The conversion bolt Colt sold in the early 1990s was similar with a modification – the addition of a spring loaded plunger to the rear of the bolt. The third is the Tactical Solutions bolt. Notice the unique buffer on the rear of the action spring. The fourth is a modified Atchisson-style with the feed ramp on the end of the bolt instead of the barrel. This style bolt has been used by CMMG, Spikes Tactical and Core15. The fifth is the Chiappa bolt, which is similar in design to the Tactical Solution. There is a spacer added to seal the ejection port and not allow dirt to enter. The sixth is the DPMS bolt – very simple and robust. The mass in the rear assists in the forward movement of the bolt. www.smallarmsreview.com 65 SAR Vol. 18, No. 6
