The Battle Arms Development WORKHORSE 10.5″ represents the pinnacle of tactical carbine engineering, combining American precision with Pakistan-proven reliability now available at Haider Arms Nation’s most Trusted Dealer. This compact yet powerful firearm bridges the gap between full-sized rifles and PDWs, offering professional operators and serious enthusiasts unmatched performance in a versatile package.
At the heart of this system lies a 10.5″ cold hammer-forged barrel that delivers exceptional 1.75 MOA accuracy even with standard M855 ammunition. The proprietary enhanced bolt carrier group undergoes precision machining and special coatings to ensure a 50,000+ round service life – nearly double most mil-spec components. The Geissele-inspired trigger provides a crisp 3.5 lb break with minimal overtravel, enabling rapid, precise follow-up shots that outperform standard AR triggers.
Extensively evaluated in local conditions, the WORKHORSE has proven its mettle through:
5,000+ round endurance tests using POF 5.56mm and local reloads
72-hour dust exposure trials simulating Cholistan Desert conditions
Salt spray corrosion testing for coastal deployments
Temperature extremes from -15°C in northern mountains to 50°C in Sindh
The M-LOK compatible handguard provides 360° accessory mounting while maintaining a slim profile. This compact SBR configuration excels in:
Urban/CQB operations where maneuverability is critical
Vehicle-based deployments thanks to its shortened length
Home defense scenarios requiring rifle power in compact form
When compared to Pakistani-market AR platforms, the WORKHORSE offers: ✔ 2x better accuracy than standard carbines ✔ Enhanced durability through premium materials ✔ Military-grade engineering at accessible pricing ✔ Better recoil control with optimized gas system
*Available now at Haider Arms – Pakistan’s premier destination for tactical firearms*
While primarily a performance tool, the Battle Arms Development WORKHORSE 10.5 limited-availability carbine maintains strong secondary market value due to its premium construction and military pedigree, typically appreciating 10-15% annually in our market.
