Pressure Plug:

These parts provide pressure against the back of the 22lr bolt carrier group and increase reliability of both conversions and dedicated 22lr uppers.  Our novel quick insert design allows for one handed insertion and removal without the need for tools.  Simply line up the insertion slot with the buffer retention pin, slide the plug into place and rotate 1/4 turn until the pin sits in the slot of on the solid front face of the plug.  Removal is is done in a similar manner, pressing in the buffer plug slightly and rotating the plug until the pin lines up with the insertion slot. The part can be inserted either direction, but we recommend inserting the side with the hollow cavity towards the buffer and the solid face towards the bolt carrier group.

Charging Handle Insert:

Our innovative charging handle insert reduces malfunctions and gas blowback.

Power Extractor (with springs):

Our 22lr Power Extractor help your rifle to have better extractor bite and increased live round extraction reliability on a dirty chamber or with waxy ammo (Golden Bullets, Armscor, Wolf Match, etc.). Level 1: 200% extractor force, Level 2: 500% extractor force.

Premium Cresent Firing Pin (with spring):

Our newly released round tip pin for increased ignition reliability.  The back of the pin is profiled to center the hammer impact for longer firing pin life as well as reduced chance of out of battery detonation.  Turned on a precision Swiss lathe from carefully selected high strength steel and then heat treated to our proprietary specifications.  Includes one firing pin spring.

Bolt Buffers:

The BoreBuddy bolt buffer prevents the bolt from slamming into the backplate when the rifle is fired.  This reduces the noise generated by the cycling of the bolt and reduces wear and tear to the bolt and the lower receiver.  When shooting suppressed, a noticeable decrease in sound level has been reported.  Buffers are consumable and for best buffer life, standard or subsonic ammunition is recommended.

Adjustable Bolt Weight:

Gen 4 is here!  It’s everything Gen 3 was, but much more robust and features toolless internal weight adjustment! Our 22lr AR bolt weight system reduces bolt velocity, delaying case ejection and reducing the volume of gas and powder residue released from the ejection port, while eliminating the infamous 22lr AR bolt bounce.  The bolt weight engages our bolt buffer at the rear of the BCG, further reducing noise and harshness for a truly refined and reliable system.  With a weight, your rifle stays much cleaner, as well. The lightweight adjustable bolt weight allows the addition of .55oz to 1.2oz of weight while offering great bolt bounce elimination.  The lighter aluminum body allows the user to use heavier internal weights for superior bounce mitigation when using short barrels and/or light ammo.  Includes aluminum and steel internal weights.

Please note: There are a lot of variables in cycling of the AR22 platform, with ammunition selection being the largest of those variables.  A lightweight adjustable weight is recommended for use with short barreled builds and/or reduced power ammunition in a longer barreled build.

Recoil Spring kit:

Adjust bolt return speed and tune for different ammo using our 3lb, 4lb or 6lb spring.

The Reliability Kits are designed to fit dedicated rifles and conversion kits with a Atchisson/Ciener/CMMG/Spikes style bolt.  See bolt weight warning for Ciener bolts: Please click here for details
