Gen 2 Enhanced Compact Buffer Tube, Spring & Buffer for Viper PDW Stocks & Braces

Black Rifle Arms patented Enhanced Compact Buffer Tube, Spring & Buffer Tube Assembly allows for Strike Industry Viper PDW Stocks and Braces to be finely tuned with different buffer weights from Carbine, H2 and Pistol.

Our pistol buffer enables the Strike Industry Viper PDW stock and braces to run pistol calibers. The receiver extension (buffer tube) is 5 5/8" in overall length. This kit is a drop in replacement and you can utilize the Strikes cheek piece, as well. The H2 buffer ensures reliable operation with select-fire weapons.

Kit Includes 1-Qty each:

Spring
Buffer Tube - Gen 2

Flutes on receiver extension allows Strikes Cheek Rest to be utilized
Hybrid tube has a relief cut to enable the use of an End Plate and Castle nut should it become necessary to convert to a pistol tube. (See our Compact Pistol Tube Kit)
Machined from Aircraft quality aluminum billet
Mil-spec Hard coat anodized finish

Buffer (buffer weight options)

Carbine Buffer weight 3.15 oz
H2 Buffer weight 4.60 oz.

H2 Buffer is recommended for full-auto use

Pistol Buffer weight 7.45 oz

Q: Do all the options come with a buffer tube. I'm confused and the description it's pretty vague on what's included with the 3 different options. I need a new buffer tube for my viper pdw. Does the first option include the buffer tube as well?

Asked by: Alex V. - 8/22/2023

A: With this package you get the buffer tube, spring and then you get to choose 1 weight size buffer either the Pistol Buffer, Carbine Buffer or H2 Buffer (we are currently out of H2 buffers so this option will not show in the drop down box under Buffer Weight Option).

Q: Does the tube have the same QD slot and drainage hole like the original tube from SI?

Asked by: Steven - 5/12/2023

A: We have a drain hole, but we do not have the QD Slot on the buffer. In order to do the QD slot we would have to make our buffer tubes longer and with SI having the QD slot on the brace body we feel leaving the buffer tube length as compact as possible is what most customers are looking for.

Q: Will any of these help with a 300blk build? Or are they stiffer springs.

Q: What buffer would you recommend to use this kit on a 7.62x39 with a 8.5 inch barrel? Thanks

Asked by: Raymond Juarez - 9/13/2022

A: Depends on how it is gassed so either carbine or h2. We run ours on h2.

Q: When will the H2 spring and tube combo be in stock?

Asked by: KrisM - 9/7/2022

A: Sorry we missed your question. We were working on building a hybrid stock for this PDW so if ATF banned them you could take the Strikes stock off and use the tube for pistol so we have made some changes and expect it to go back back in stock sometime this coming January.
