Finally, a closer look at the Clandestine Airsoft custom batch, Lonex 14.5" M-4 RIS [ame]http://youtu.be/JC8JT7B78F8[/ame] ***Things I missed in the video:*** - AEG comes with a standard LE collapsible stock, *not* the Crane stock I was using. - AEG also comes with a very nice instruction manual and cleaning/unjamming rod. - Metal parts are a very dark matte black. About the same as real-steel black anodizing. - Receiver pins are captured. - Zero receiver play, RIS wobble, or barrel wobble. The rattling you hear is just the stock and battery. - Magwell is a bit wide, allowing some side-to-side wobble, but fits a wider variety of mags. - Motor grip is vented for enhanced heat dissipation. - 3x rail covers are included. ***Notes:*** - 360-365 FPS with EliteForce 0.25g Bio and hopup set to flat trajectory. Shot over Xcortech X3200 with fresh batteries. - 20.1 RPS with 7.4v 2200mah 25C nanotech, charged to 8.28v - 32.6 RPS with 11.1v 1000mah 40C SKY, charged to 12.28v - 34+ RPS with 11.1v 40c 3000mah SKY lipo, somewhat drained, mini-Tamiya connector. - AoE is correctly set from the factory - Piston weight is a VERY heavy 25.98 grams, DO NOT PUSH THIS AEG PAST 30 RPS. - Feeds well from included Flash Mag; basically 100% feeding until the last couple dozen rounds, where there is some skipping. - Accuracy/range as yet untested.
