Please Note:  This gun has a BLACK stock and grip!   We're updating the picture shorty.

The M4 RIS shorty for close quarters use is a full metal compact high end AEG.

Bolt are a relatively new manufacturer of high quality full metal airsoft rifle AEG's who specialise in a patented new electric blow-back (EBB) system on all their rifles. The Bolt Airsoft system has been named Bolt Recoil Shock System (BRSS) which produces kinetic energy from the gearbox and transfers that energy down through the receiver and into your body through the stock.

The Bolt Airsoft rifles offer truly amazing quality for your money, with extremely realistic metalwork and attention to detail. The entire body is constructed from aluminium, alloy, steel, ABS pistol grip and glass fibre reinforced stock. You are not going to break one of these! Even the outer barrel is a one piece design offering superior accuracy and zero barrel movement.

Bolt are not hiding any reduced quality parts inside their rifles to bring the manufacturing cost down either. The front-wired vII gearbox is a work of art! Forged steel gears seated in low friction 8mm bearings will handle the cycling all day long. You've even got an aluminium spring guide, one piece metal hop-up unit, high torque motor precision inner barrel, are you getting the idea?

Here's the deal clincher: Bolt Airsoft rifles are TM compatible. That means you can upgrade to your hearts desire, if you really feel the need to get better than what's available out of the box. They accept mainstream TM compatible magazines, with a 600rd AK hi-cap included.

As you've probably guessed, we are really excited about this product line. Bolt Airsoft kick pretty much every other manufacturers arse, not only with the awesome EBB recoil but simply through value for money. We are struggling to come up with a suggestion that even comes close to the quality and price combination offered here.

First skirmish of this weapon today so will update review once cracked open the gearbox.
The BBRS gives a grin factor that could rival the jokers smile. The best kit in the market to date in my opinion. The feel of the thud in your shoulder is comparable to a 22 rifle and seriously turns heads.

The build quality of the gun externally is some of the best iv seen, owning other mid to top end guns I can say that a lot of thought has gone into the external materials and look.

The rifle was not rear wired which was a shock having looked at reviews and the picture, however the ability to swap the handguard out and use another gave huge battery space, 1600mah 9.6 and 3s 11.1 lipo no issue.

Would recommend this gun to anyone.

Review by
Fantastic gun. Mine fired at 335 fps out of the box. Had to have it lowered to make it site legal in N Ireland. Really sturdy, feels well put together and solid. Nice rate of fire and incredible accuracy even at range. It is so accurate at range I have just bought a scope for it. It is sold as a cqb gun but personally I have found it more suited to mid / long range as the length of the gun doesn't allow fast turning when entering buildings etc. Absolutely fantastic value I am really pleased with this purchase and would recommend to all.
