[Details]
 
In recent years, various manufacturers have developed AR15 short-stroke kits (e.g., DFA MCS2.5", LAW TAC ARIC) and BUILD-IN RECOIL SPRING upper receiver  (e.g., BRN-180, JAKL,FM-15), 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 modern urban warfare or 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. Cost Advantage:
Converting an AR15 into a bullpup using our kit is far more cost-effective than buying a complete bullpup rifle. For instance, the TAR-21 sells for about $1800, whereas an AR15 converted with our kit can cost under $1000, thanks to the abundant aftermarket parts for AR15s. Our kit is priced at just 60-70% of our competitors' kits, yet it looks cooler and is manufactured with superior craftsmanship.
 
3. 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.
 
4. Versatility:
Our kit is compatible with any AR15 safety selector and grip, significantly increasing customization options.
 
5. Exclusive Patented Magazine Release Button:
Designed for ambidextrous operation, our magazine release button offers superior ease of use compared to competitors.
 
6. High Compatibility:
Our kit is adaptable to most AR15 models, offering broad compatibility, whereas competitors' products only fit specific AR15 configurations.
 
[Compatibility]
 
1. The SARB-15 bullpup chassis kit does not include an AR-15 lower receiver. This kit only supports Mil-Spec AR-15 lower receivers.
 
2. The SARB-15 bullpup chassis kit does not include an AR-15 upper receiver. This kit supports upper receivers with a built-in recoil spring (e.g., BRN-180, JAKL, FM-15) or AR-15 upper receivers that have a short-stroke BCG installed (e.g., DFA MCS2.5", LAW TAC ARIC, CMMG 5.56 to .22 BCG).
 
3. The SARB-15 bullpup chassis kit does not include a short-stroke BCG. Please contact Dead Foot Arms, LAW TACTICAL, or CMMG to purchase the necessary parts.
 
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.
 
5. To install the JAKL upper, it is crucial to purchase the BUFFER STOP kit separately. Failure to install the BUFFER STOP kit can lead to severe firearm malfunctions and pose risks of injury or even death.
