After the success of the Generation 1 Battle machine, Valken poured a huge amount of R&D and improvements into the SRC manufactured Gen 2 design.
Valken's battle-tested AEGs now feature significantly improved internals and externals asked for by the airsoft community. These features include:
Redesigned Motor Grip
Shimless design with an extra large adjustment screw makes it easier to adjust motor height with less chance of losing the motor plate shim.
Vented motor plate for extra cooling to prolong the life of the motor
Improved Gear Set & Piston
30% increase in gear strength due to 20% thicker gears and better materials
Stricter manufacturing tolerances and QC to ensure teeh are meshing perfectly
Piston upgraded to have 6 metal teeth to prevent stripping
Barrel and Hop Up Overhaul
7mm Hop up Clip for better retention and stability
More secure hop up adjustment wheel for eliminating hop-up drift
CNC barrels are now much more accurate and consistant from shot to shot
Revamped Trigger Assenmbly
150% stronger components offer significantly more resistance to wear and tear
Improved trigger for smooth and consistant trigger pull
In addition to all of those improvements, Valken and SRC have added some awesome new externals. The unique Valken multi-position crane stock easily fits most nunchuck or crane style batteries and is vented to keep batteries cool during intense full-auto firefights. The Keymod & Picatinny wire-cutter style RIS combines the best of both worlds: A modular KEYMOD side rails as well as picatinny/weaver upper and lower rails. High visibility flip up front and rear iron sights improve aiming at targets near and far even in low-light conditions. The externals are nylon-reinforced polymer which maintains it's durability yet cuts the weight and pricetag of the rifle significantly.
