The India has every single feature they offer for a semi-auto .22LR conversion. Kit Includes: Right Handed Stainless Steel Action, 22 ECL (Evolution Chamber Lock), Live Round Extraction, Buffer Retaining Pin Relief Cut, Piston System Compatible (without removing piston rod), Magazine Stabilizer, Bolt Hold Open Actuator, 25 Round Magazine, Charging Handle, Removable Forward Assist, Extension Bushing, Stainless Steel Cleaning Jag/Guide Rod, Go/No Go Chamber Adapter, Compatible with Any Mil-Spec AR15 Upper, Magazine Loader. The Evolution Chamber Lock is a brass chamber adapter that locks into place eliminating all play between the conversion and upper receiver which has two beneficial effects. First, by eliminating all play between the conversion and receiver, reliability is improved. Secondly, for trainers and armorers, it makes it more difficult to remove and "tinker" with the conversion which greatly reduces down time due to "unauthorized" cleanings or dis-assembly.
