SRC M4 SR4 ST-Alpha Sportline Polymer AEG Gel Blaster - Desert Tan


SRC Sportline Series - the perfect rifle for ambitious Gelsoft beginners!

This rifle is based on the well-known SRC Sport Line series and ensures a very good price-performance ratio. A product line that is primarily intended for ambitious newcomers to the gelsoft world. 

In addition to a particularly robust main housing made of polymer composite plastic, there are also important external attachments and the gearbox made of aluminium. 

The front of this gel blaster rifle is equipped with a one-piece approx. 13.6 inch outer barrel with standard M4 sights and M4-style flash hider. The parts mentioned, including the delta ring, are made entirely of metal and thus ensure very good stability. 

The aluminium stock tube at the rear end, with its 6 locking positions, ensures that the rifle can be perfectly adjusted to the shooter. 

Inside is a stable Reinforced Version 2 metal gearbox in a 6mm design. The rifle is of course not only equipped with a semi-automatic, but also with a fully automatic shooting function.

* Battery and Charger not included*

Tactical Edge Hobbies is the largest supplier for all your Gelsoft needs! 

Always use the appropriate eye wear and take all reasonable safety precautions when using our products.

Charging Batteries

When charging the batteries, we recommend charging them between 1-4 hours.

When they are charging the light/s will flash and once it is fully charged, the light/s will turn a solid red or green.

Also, once you hear the battery getting flat, please recharge it as running it flat can damage the cells.

Soaking & Storage of Gels

When soaking the gels, they need to be soaked fully submerged in warm water from the tap for a minimum of 4-6 hours.

Once they have fully grown you can leave them in the water and keep them in or out of the refrigerator.

When you are ready to use them just drain off any excess water with a strainer before you feed them into the mag but do not dry them as they need to be lubricated to work correctly.


Do not upgrade any part of your toy gel blaster as this will void the warranty. Upgrades refer to pulling any of the blasters apart or opening it up, changing springs, or upgrading the battery from 7.4v to an 11.v battery.
