SRC SR4 ST Mamba P1 M4 17" AEG Gel Blaster Rifle Replica - Black - SR4-M-P1-BK

Product Description
Maximum quantity available reached.

The SR4 ST Mamba P1 Gelsoft Rifle from SRC has an immaculate finish, is stylish, sleek, extremely imposing and aggressive with its 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 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 this seriously foreboding 17" 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 muzzle velocity of 330+ fps out of the box!

This model is an automatic electric gel blaster (AEG). The battery fits in the back of the buttstock. Just slide the battery into the compartment. The battery, wires and connector must be placed whole inside.

SRC is one of the market leaders and continually invests in improving and developing its gel blaster products. A sensational finish and incredible accuracy is what you'll get with this Rifle from SRC.

When you purchase products from ViperTac, you can be sure that you are purchasing a high quality, reliable product with a 30-day warranty and a dedicated experienced team of gel blaster addicts (I mean enthusiasts!) to assist you with what you need.
