S-MAG Design and Textured Polymer:
If you are looking for a universal magazine that combines an aggressive aesthetic with extreme capacity, the S-MAG series from Specna Arms is the ideal choice. The outer shell is molded in robust polymer, a material that drastically reduces the weight on your equipment. The entire side surface is covered with a non-slip texture formed by the Specna Arms logos, ensuring a rock-solid grip even when wearing thick gloves or in conditions of high humidity. Its elongated and slim profile has been specifically designed not to get stuck in the tight magazine pouches of the plate carrier.
Impeccable Feeding and High Performance:
Inside this polymer gem hides a Hi-Cap mechanism designed for intensive use. The tank holds a good 380 BBs, ideal for long bursts of suppression (spray-and-pray) without the thought of having to reload continuously. The real strength of the S-MAG, however, lies in its high-quality loading spring: it is capable of smoothly feeding replicas even with extreme rates of fire (RoF exceeding 25 BBs per second) and effortlessly manages even heavy BBs (from 0.30g upwards).
WARNING - SPEEDLOADER DANGER: Specna Arms is categorical on this point! Never use a speedloader (syringe loader usually used for mid-caps) to insert BBs into the outlet hole of this Hi-Cap magazine. This operation irreparably destroys the internal feeding mechanism and instantly voids the product warranty. Simply open the top flap and pour the BBs in.
Specna Arms Synergy: Although this magazine is compatible with most brands on the market, it is considered the "Best choice" if you own a rifle from the Specna Arms PRIME™ line or their other series (Edge, Core, etc.). The millimeter dimensions have been designed specifically on their receivers to eliminate any "play" in the magwell!
High rate of fire: This magazine is a real monster and will keep up with you even if you have had your replica prepared by a technician with fast gears (25+ BBs per second). Rotate the wheel on the bottom until you feel a mechanical hardening, then be ready to unleash hell on the field!
