The Boyi D-Boys M4 SIR is plastic bodied gun, which includes a monster of a rail. The rail extends over the entire top of the gun. It also has additional rails on the sides of the forend, and on the bottom of the forend. Additionally, a vertical foregrip is included. Features also include a folding rear and front sight.


As there are many people interested in the mid-level airsoft guns, and more and more “Marui Clones” and “Chinese knockoffs” are hitting the shops, I decided that AP could benefit from knowing more about them. I have been interested in the S-System and decided to pick up the BOYI version of this gun from www.airsplat.com

This is a great gun for an entry/mid level airsoft player. In comparison to Tokyo Marui, I would recommend it as a comparable alternative. It comes with all the components necessary to use it right out of the box. Two areas where I was disappointed were the plastic flash hider, and the light weight plastic butt stock. It is upgradable, but may not withstand high FPS springs.




PROS:
  • 330 FPS with decent rate of fire.
  • Plastic receiver is a durable plastic.
  • Alan type receiver pins
  • Metal rails, very durable.
  • Metal front and rear rifle sights
  • Heavy gears. The gears seem more durable than stock Tokyo Marui gears.
  • Metal hop-up chamber
  • Removable sling mounts on stock and foregrip.
  • Systema clone piston.
  • AEG Gear box comes very well lubricated.
  • Top of barrel threads off for suppressor
  • Spring guide soft plastic, but it does have a aluminum base, better than stock Tokyo Marui spring guide rod.
  • Metal trigger stop inside gear box (plastic on Tokyo Marui, CA, and ICS).
CONS:
  • Plastic flash hider comes glued on. Difficult to remove, but not impossible.
  • Retractable LE style but stock is made from very light weight plastic, kind of flimsy.
  • Plastic bushings. (pictures are shown with replacement metal bushings.)
  • Front sight does not completely lock in the upright position, but it is pretty sturdy.
  • Gear Box Cylinder is not ported. This is not always a bad thing, but with a longer barrel it can create suction and lose FPS.
  • AEG Gear box is very light. May not be the best for upgrading to high velocity, not recommended for a metal piton head.
  • Upper receiver is proprietary for this gun, not compatible with other AEG front ends.
  • Rail system is not compatible with other guns unless custom modification





Comes with:

8.4 mini-type battery
Nylon sling
300 round hi-cap
Standard wall charger
Vertical grip
Unjamming Rod
