The M4 morphs into an AK! Well almost as the only real difference is that the lower receiver has a customised mag-well which accepts TM standard AK magazines. Of course on the real steel firearm there are much more internal changes because it is adapted to chamber the 7.62 Soviet round instead of the M4 norm 5.56 NATO.

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 rear-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 Impressions... Very good.

After changing it to deans and using a 7.4v 2600 lipo it runs very nicely. Trigger response is great for a stock rif. I play alot of CQB, so fast trigger pulls is a must! The Bolt SR47 not only takes it (doesn't lock up without modifications like other brands iv used) but with the EBB mixed with the recoil its very realistic! Not to mention so much fun! Not had chance to break out the chrono yet so i don't have a "out the box fps" sorry... Range isn't to bad for CQB play (outdoor might be different though) I do highly recommend using Lonex AK flash magazines with this. They feed perfectly

Unless otherwise stated, all products are sold singly.



Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).
