Replica & Modifications
I initially bought it as a basic M4 RIS Katana System because of its pragmatic fast cylinder switching system, allowing the user to tailor the replica's FPS in seconds before a game to comply with terrain regulations.
From there, I removed the external barrel extension to shorten the replica's length. I installed a CNC hop-up unit, a new soft hop-up rubber and a 300mm 6.01 precision inner barrel. These modifications have boosted its effective range from 50m to about 60m. To increase the rate of fire and reactivity, I also installed a hi-torque motor coupled with a MOSFET unit. The replica runs with a 7.4V 25C 2000mAh nunchuck li-po battery with sturdy T-plugs (deans) connectors. With a red cylinder it shoots at 375 fps at a rate of 1000 BBs per minute and with the blue cylinder it shoots at 315 FPS at a rate of 1200 BBs per minute.
I simply love its reactivity in semi-auto, its precision, range and the impressive rate of fire in full-auto. It is short enough to work well in CQB and has enough range to hit targets in closed and open areas alike. As I am very familiar with AR platforms, for me, it's ease of use and flexibility are valuable attributes.
Magpul MOE Rail Vertical Grip: this sturdy vertical grip allows me to grab my replica in different positions depending on the terrain configuration. I mainly use it as a handstop to have maximum stability, especially in open field areas.
Ergo ladder rail covers: I like these rail covers because they are low profile and do not fatten the replica's RIS. Their soft rubberry texture protects my hands and gear from the abrasive rails and also provides more grip when I'm using gloves, especially when wet.
AN/PEQ 15 replica: this fake laser designator is just for show as it is an empty case. I will probably replace it with a green laser / flashlight combo box in future.
JJ Airsoft Micro T-1 red dot sight: a very handy reflex sight that comes with lens covers and a nice meshed kill flash. I love the QD mount and the tool-less dot adjustment systems. The dot is very bright and definately helps with follow up shots in low light environments like indoors CQB.
Troy Backup rear iron sight: a beautiful CNC machined iron sight that I have used a lot as a primary sight before buying the red dot. It is very sturdy, easy to configure and locks nicely into place.
Magpul ASAP sling mount: I am not a fan of the standard M4's sling mount options, so I removed the noisy front sling attachement and replaced the lower receiver's back plate with this handy ambidextrous sling mount. It allow me to perform faster shoulder transitions and thus shoot with both right and left hands on the fly - a useful skill in CQB, since transitions allow you to reduce your body's exposure to opponents.
E&C Real Cap magazines: for realism's sake, I replaced the flimsey metal hi-cap mag that came with the replica for a boxed set of 5 real cap 30 BBs magazines. They are lightweight, silent and, in truth, shoot about 27 BBs - the last three fall out of the hop-up unit when you reload which is typical with most AEG replicas. I really love using these magazines as they force me to count my rounds, perform tactical/admin reload and conserve ammunition. Overall, they are great for training and skirmishes alike.
