CONVERSION KIT ACCESSORIES
All of theses accessories come standard with the Model INDIA.
BHOA
The Bolt Hold Open Adapter keeps the bolt open after the last round is fired. It allows for full function of your rifle's existing bolt catch. This Adapter only works when used with a CMMG Evolution Magazine. | Forward Assist Adapter
The Forward Assist Adapter allows the use of your existing forward assist to push the .22 bolt forward manually if necessary. Comes standard with Echo and India Kits.
| Locking Lug Kit
The Brass Lug rotates and locks in the barrel extension. This eliminates play between the conversion and the receiver. Attaches only to Stainless Steel Kits. | Guide Rod/Cleaning Jag
The Stainless Steel Upgraded Guide Rod can also be used as a Cleaning Jag. Comes standard with Echo and India Kits.
| Charging Handle
The Anti Jam Charging Handle for Drop in Conversions was designed to prevent spent 22 casings from jamming between the charging handle and the bolt. The groove on the bottom of the charging handle is much more shallow compared to a standard AR-15 handle. | Mag Loader
This makes loading your .22LR Magazines easier. No more sore thumbs at the range.

22 EVOLUTION MAGAZINES
The 22 Evolution Magazines have a semi transparent core, steel feed lips, and a polymer skin. All of the Evolution Magazines are compatible with the BHOA and are available in 10rd and 25rd configurations.

22 BARREL & BOLT OPTIONS
The .22 Chamber Adapter and .22 Collar can be interchanged on any .22 Bolt Group. This allows the user to change a Dedicated Bolt into a Conversion Bolt and vice versa. The Chamber Adapter is needed when using a 5.56 Barrel and the Collar is needed when using a .22 Barrel.
When a dedicated .22 Barrel is secured into the receiver, the Barrel Chamber recedes into the receiver. The Dedicated .22 Bolt Group engages and secures under tension to the .22 Barrel Chamber. This accomplished with the spring loaded detent in the .22 Collar.
