SRU SARB-15 Bullpup Kit for MTWs or GBBR (AIRSOFT VERSION)

Notes from JollyFancher:

These kits were designed to fit GBBRs, but the Wolverine MTW uses a Milspec Lower, so the Gen 1 and Forged Series fit without any modifications! We are also working on a 3D printed kit to install a G&G lower, but this will require an HPA engine to be installed. 

How do I know if I have a Gen 1 MTW?

The Gen 1 MTW has either the Wolverine Logo on it or the Gen 1.5 has the mascot, Cuddles, on it. These both have a Forged Lower with a removable trigger guard. These will fit the Billet version, but modifications are needed, mainly cutting the trigger guard off.

Its a bullpup, the trigger must be awful right?

The trigger is surprisingly good and feels smooth, one of the best bullpup triggers I have used. SRU reports that a curved trigger is required, but for the MTW with its adjustable trigger, the stock flat or Maxx Trigger will fit perfectly fine.

SARB-15 Airsoft version

Warning!!  Do not install the AIRSOFT version of the SARB-15 CHASSIS on a real AR-15 firearm. The materials used in the AIRSOFT version are not designed to endure the recoil and high temperatures generated by a real firearm. Improper use may result in serious injury or death.

In recent years, various manufacturers have developed AR15 short-stroke kits for GBB AR15 airsoft (e.g., Maple Leaf Hummingbird bolt, Airsoft Monster/GBL short bolt and C&C tac short bolt/SRU S.C.S. BOLT) , allowing AR-15 to be fitted with folding stocks.

However, we see another possibility: converting the AR15 into a bullpup rifle.

The biggest advantage of a bullpup rifle is that it significantly shortens the overall length of the firearm while maintaining the same barrel length. This brings the center of gravity closer to the operator, greatly enhancing maneuverability. This advantage is particularly evident in close-quarters combat (CQB).

The advantages of our product are as follows:

1. Exceptional Industrial Design and Ergonomics:

Our kit seamlessly transforms the AR15 into a bullpup rifle, enhancing its futuristic style. Compared to competitors' kits, our professional design far surpasses the amateurish, garage-made feel of theirs.

2. Exclusive Patented Trigger Linkage Design:

Our rotary lever design reduces the trigger pull weight, allowing the front trigger to be easily replaced with any AR15-standard trigger available on the market.

(The airsoft version uses a 304 stainless steel stamping process.) 

3. Versatility:

Our kit is compatible with any AR15-spec trigger, safety selector and grip, significantly increasing customization options.

4. Exclusive Patented Magazine Release Button:

Designed for ambidextrous operation, our magazine release button offers superior ease of use compared to competitors.

5. High Compatibility:

Our kit is adaptable to most AR15 models, offering broad compatibility, whereas competitors' products only fit specific AR15 configurations.

2. The SARB-15 bullpup chassis kit does not include an AR-15 upper receiver. This kit supports upper receivers with AR-15 upper receivers that have a short-stroke BCG installed (e.g., Maple Leaf Hummingbird bolt, Airsoft Monster/GBL short bolt and C&C tac short bolt/SRU S.C.S. BOLT)

3. The SARB-15 bullpup chassis kit does not include a short-stroke BCG. Please contact Maple Leaf, Airsoft Monster/GBL, C&C tac or SRU to purchase GBB short bolt sys.

4. The SARB-15 bullpup chassis trigger linkage system is compatible with single-stage or 2-stage AR-15 trigger sets. However, please note that the trigger must be a curved type and not a flat type.
