KWA would like to introduce their smallest, lightest gas gun to ever be released; the Limited Edition LM4 KR7 Stinger! Like the other rifles in the LM4 Series, the Stinger comes fitted with the same robust and super-realistic internals that are proven quality. This CQB weapon has an integrated lightweight aluminum KeyMod rail system that reaches down the gun to meet up with a full metal mock suppressor over a 5 inch barrel, giving you the ultimate edge on any battlefield. The KR7 Stinger has the same specs as its brother, the PTR, but features a longer rail system for more upgrades and customization. The PTS Enhanced Polymer Grip ensures you're given optimal grip in any weather and battle conditions, and reduces player fatigue by offering a softer grip platform. The KWA LM4 Series features a new hop up system that was developed for the original LM4 to improve range performance and account for wind conditions. An aluminum alloy receiver houses the full steel reinforced bolt carrier for strong reliable feedback. Utilize the adjustable stock to modify the rifles overall length for players of any size, or adjust for CQB and Long Range engagements. The LM4 KR7 buffer tube has the same diameter of a MilSpec Butt Stock which allows players to customize thie rifle to their specific weapon configuration. The universal lower receiver can also accept aftermarket AR15 Pistol Grips and Trigger Guards. The realistic blowback action, combined with the operational forward assist and functioning bolt catch provide each user unparalleled realism by mimicking fundamental AR15 weapon manipulation. Similar to real AR15 style rifles, the KR7 modular design allows limitless customization options to best suit the individual's training needs. By Combining a rugged metal build with the power and accuracy needed to out-gun the competition, KWA has created an AEG that will surely resonate with players of all skill levels and play styles.
