Description
Secutor Arms Centurion IV MWS GBB Airsoft Rifle Black
The Secutor Arms Centurion IV is a black gas blowback airsoft rifle, listed as MWS compatible. It sits between the Centurion III and Centurion V in Secutor’s line of M4-style gas rifles, and it offers the realism that draws players to gas: a bolt that cycles with every shot, a kick you can feel in the shoulder and a sharp report.
The MWS listing matters because the Tokyo Marui MWS layout has become the reference point for gas rifles, so the Centurion IV gives you a good starting point for spare magazines and future upgrades. In black, it is an easy rifle to build a loadout around.
Compatibility
Use good quality seamless 6mm BBs and the gas recommended in the manual. Gas blowback rifles need gas magazines made for their own system, so AEG magazines will not fit. Optics, lights, lasers and grips can be fitted to the rails or handguard where there is space; check the product images for the exact layout.
The Centurion II magazines we stock are listed for the Centurion II, and MWS-pattern gas magazines are generally the place to start for spares. Fit can still vary between brands and versions, so test any new magazine before relying on it in a game, or contact us and we will check for you.
Care and maintenance
Keep the bolt carrier and the inside of the receiver lightly lubricated with a suitable silicone-based gas blowback lubricant, and clean the inner barrel now and then with a rod and dry patch. Avoid getting oil on the hop-up rubber, and use only good quality seamless BBs.
Put a drop of silicone oil on each magazine’s fill valve and seals every few fills, store magazines with a little gas in them so the seals stay tight, and never overfill. Store the rifle unloaded with the magazines removed, somewhere dry and away from direct heat or sunlight.
Who is it for?
The Centurion IV suits players who want a realistic M4-style gas rifle for skirmish or milsim, with the backing of the MWS layout for magazines and parts.
Please note: The listing does not say which magazines or accessories are included, so please ask us before ordering if you need to know. Always wear suitable eye protection when using any airsoft replica, and have it chronographed at your site before play.
