These are very solid high quality blasters and are excellent for new and experienced players. 

The SR4 ST Mamba P1 Gel Blaster Assault Rifle from SRC has an immaculate finish, is stylish, sleek & extremely imposing and just the right amount of aggressiveness with it's hybrid MLok/Picatinny system on a super long, but extremely comfortable handguard. SRC definitely provides a quality product well above its price tag. You won't suffer buyer's remorse with this bad boy! 

The sights are Rhino Style, flip up sights. In the closed position you have battle sights with optic fibre for quick target acquisition. When the sights are flipped up, they become traditional peephole and front blade M4 'iron' sights.  

The gearbox is a reinforced V2 configuration and is capable of semi-automatic/full-automatic & Safe mode via the fire selector switch.

This gel blaster features a 20mm RIS picatinny rail system on the top and underside of the handguard, perfect for attaching a plethora of accessories, such as holographic sights, 3 x magnifiers, scopes, canted sights and flashlights or foregrips. It reaches a speed of 330+ fps out of the box!

This model is an automatic electric gun (AEG). The battery fits inside the Buttstock. Just slide the battery into the compartment. The battery, wires and connector must be placed whole inside the breech cover. Replace the cover using the opposite movement.
