Get your trigger fingers ready for the long awaiting replacement Upgrade bolt.

The exterior of this bolt is produced to a far superior quality standard over a stock bolt too. Expect a smoother and more stable bolt pull shot after shot with this upgrade. The internals of the bolt include a steel spring guide that is bearing braced to keep your shots consistent too. The piston is also steel and when all combined, you are going to have a demon of a rifle out on the field. The internal spring is still AEG compatible too, so if you want to boost the power just a bit more, you can with a simple AEG spring.

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
