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 Round-tip Firing Pin (with spring):

Our newly released round tip pin for increased ignition realiablity.  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:

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 adjustable bolt weight allows the bolt weight to be tuned from 6.2oz to 7.6oz (similar to tuning using H1, H2, or H3 configurations in a standard centerfire AR).

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

    Details: Standard AR with in .223wyld with CMMG conversion kit. Used federal bulk pack and had several issues with extraction, failure to feed, failure to fire at a rapid pace (bolt bounce most likely) and general feeding issues with standard mags. I could have used better ammo but I refuse to buy fancy .22lr ammo.

    Before many of the parts in this kit were available I had ordered the bore buddy standard reliability kit that had the buffer piece, the buffer plug, charging handle insert and some stiffer extractor springs.

    Shot this a bunch and still every once and a while I would have malfunctions I associated with the crap ammo. I felt like you could only get so good with .22lr.

    Then I purchased the “stimulus package” shown here. Along with a CMMG dedicated .22lr barrel which eliminates the gas block and has a proper twist rate for .22lr and a TACOM competition recoil spring to finish it off. (patiently waiting for a selection of springs….)

    In short, 350 rds later which included federal bulk pack, Winchester bulk, Wildcat bulk, CCI stinger, CCI segmented HP, and some 15 year old crusty corroded Remington “game load” and there was ZERO malfunctions to speak of. I though for sure the old crusty Remington ammo would choke it up but I had ZERO malfunctions in 350rds. I’m not sure how you could be any more pleased with a product than that. Also, only one drop of oil in the extractor area for assembly, other wise no oil. I also never had to oil it to continue functioning. Simply put, for 350rds it just kept going, and going, and going, without a single hiccup. The action was also much cleaner in part from the dedicated barrel not having a gas port and I believe from the extra weight slowing the bolt and keeping the action forward just long enough for more powder to burn before cycling.

    Seriously what more could you ask for.

    Of course, shipping and customer service couldn’t have been better. I had to ask about the torque of the small bolts for the adjustable bolt weight and was prompted with a funny conversation about it. Needles to say, a very carful snug with some Loctite will do and the ability to safety wire your bolts isn’t available….. yet.

    Thanks again for a great product!
