Here is what Airsoft Megastore say about the Valken Tactical MKII Alloy Series AEG in this video review. You can check their online store as well as they have this in stock... "The MK.II AEG Airsoft Rifle is finally here to join Valken's premiere line of the Alloy series. This AEG is designed to bridge the gap between CQB and outdoor environments with a mid-size 25" inch size to adapt for any scenario. The Alloy Series MK.II rolls out with durable aluminum receivers finished with a matte black layer to give a sleek design. The hard coated material provides a tough exterior to resist against abrasions and scratches. The 10" inch skeletonized free float M-LOK handguard holds the right amount of space to hold M-LOK flashlights or lasers to your convenience. On top of it all, a full length standard 20mm rail with flip-up dual B.U.I.S. front and rear sights are created with this AEG. It can also carry extra space for optic attachments to add more precision to your performance. Covering the rear is an HDP 6 position crane stock that's fully adjustable to accommodate your stability. The battery fitment can be found on the rear buffer tube by simply twisting on and off.

The full metal Version 2.1 Gearbox is built with 8mm bushings on the sector, spur, and bevel gears with an 8mm bearing space around the bevel. Additionally, the gears are shaped with an SHS 18:1 ratio. Not only that, but the internal tooth rack piston and selector plate are also made out of metal to fully benefit the life span of this AEG. This gearbox even comes with a quick spring change guide and a micro switch trigger system for a speed reaction performance. Finally, the measurement build of this tightbore inner barrel comes out to 6.03mm in diameter size for efficiency. So get in there and conquer the skirmish with your team by choosing the Alloy Series from Valken today."
