Owners of the CMMG® .22 LR Conversion Kit will, at some point, need to disassemble the kit for cleaning or to change adapters. While it may look like a daunting task, disassembly is quite easy and straightforward. Here we will show the steps to strip and reassemble a CMMG .22 LR Conversion Kit.
First, pull the bolt back with one hand and firmly hold it in the rear position. Remember the bolt is under spring pressure and will slam forward if released.
Push on one side of the carrier with a thumb, while pulling the adapter to the opposite side of your thumb.
As the carrier is pushed to the side, rotate the adapter downward and remove it from the carrier. Slowly release the bolt and slide it out the front of the carrier.
Finally, remove the spring and guide rod from the carrier.
If the firing pin needs to be removed from the carrier, remove the firing pin retaining pin from the bolt. Then the firing pin can slide out the back of the bolt. Notice a notch in the firing pin, as it will need to be reinstalled with this notch facing the hole for the retaining pin. Then simply put the retaining pin back in place in the bolt for final assembly.
To reassemble, slide the bolt back onto the carrier.
With the bolt towards the front of the carrier, insert the spring into the bolt while holding the bolt tight.
Use the guide rod to compress the spring and place the rear of the guide rod into the hole made in the back of the carrier. Once the spring is in place, pull the bolt to the rear while still holding the bolt securely. Place the adapter under the carrier and match the notch on one side of the adapter to the carrier. Push that side of the adapter into place on the carrier, then while using upward pressure rotate the bolt into place on the other side of the carrier.
Slide the bolt back and forth on the carrier and check to make sure all pieces are installed correctly. Your CMMG .22 LR Conversion Kit will now be ready for use.
