BREAK–IN PERIOD
Airsoft guns, like many other products require a “break-in” period to ensure the optimal
performance. This break-in period allows the spring, piston, gears and other moving parts
to be seated and become more consistent in their movements. Every new KM4 Airsoft gun
spring is manufactured with more tension than is required, this break-in period will allow
the spring to “settle” and operate at the specied FPS range.
The KWA KM4 Airsoft gun’s break-in period will require a minimum of 2000 rounds.
During this break-in period, the Airsoft gun will require more cleaning because it will expel
excessive grease from the gearbox. After the break-in period, the gun will operate within
factory specication. The accuracy of the brass barrel will also improve as you continue to
use the gun.

FUNCTIONS AND FEATURES
KM4A1
The KWA KM4A1 Carbine is the rst production AEG engineered specically for the
unparalleled performance of today’s advanced battery technology – Lithium Polymer (LiPo).
LiPo batteries provide higher capacity and superior performance surpassing the more
common Nickel Metal Hydride (NiMh) batteries. However, this powerful battery requires
the highest quality of internal components. To handle the extra power of LiPo batteries, the
KM4A1 is equipped with a reinforced metal gearbox utilizing KWA’s exclusive six
9mm ball bearing bushing combination and heat treated, precision metal gear sets. Heavy
duty springs and high-torque motors are matched for optimum performance. High-grade
metal alloy are used for the production of the upper and lower receivers. The KWA KM4A1
Carbine was engineered to outperform the competition, offering ultra high performance
and dependability straight out of the box!
KM4CQB
The KM4 CQB was designed and engineered especially for close quarters battle scenarios
with a 350 FPS limit. After initial break-in period, the KM4 CQB shoots consistently below
350 FPS but res more than 20+ rounds per second using .20 gram BBs. The KM4 CQB is
“LiPo-Ready” and share all the standard features found on the KM4A1. All of the internal
components have been nely tuned and recalibrated to provide the maximum rate of re
while maintaining the 350 FPS limit.
