Springs are the perfect upgrade for an instant FPS boost! They fit in most standard AEGs and have a relatively simple installation process. Many rifles these days have some sort of quick-change spring system which makes your life even easier when upgrading your rifles.

The Bolster Armouries Premium AEG Spring is the best of the best when it comes to internal springs. These are the same springs used in our Bolster Armouries rifles, that's just how premium these springs are! If you want your rifle shooting like a Bolster Armouries ONYX, then the Bolster Armouries Premium AEG Spring is certainly a step in the right direction!

Description

M90

The M90 Bolster Armouries Premium AEG Spring provides approximately 295 FPS on 0.2g BBs and is ideally suited to Airsoft AEGs intended for CQB, as the additional power is not necessary for CQB ranges. Using a lower-strength spring will prolong the life of the AEG's internals and provide a greater rate of fire and improved trigger response. 

M100

The Bolster Armouries Premium AEG M100 spring, also known as a 1 Joule spring, provides 328 FPS on a 0.2g BB, 

When coupled with other upgrade parts, such as tightbore inner barrels, an M100 spring should see an AEG shooting at near enough 350 FPS with an M100, as such we recommend this spring for 350 FPS field limits if you are likely to upgrade your inner barrel or you have already. 

M120

An M120 spring should provide around 393 FPS with a 0.2g BB. This is the spring we advise for DMR setups which are limited to semi-automatic only. With this spring installed in your AEG, you will likely need a high-torque motor and other internal upgrades due to the heightened stress this spring will place on your gearbox internals and shell. This spring is for Semi-Auto AEGs only.

When carrying out the balancing act of tuning your AEG to reach the absolute pinnacle of power it is important not to forget "joule creep". This phenomenon happens when heavier BBs are used and can cause the AEG's muzzle energy to creep up more than expected. When DMRs are chrono'd most sites insist on chronoing with the BBs you are using and will be keeping an eye on you throughout the skirmish. This is important for keeping other players safe, so please ensure you have done your sums before putting together a DMR build to avoid disappointment!

Size guide

Parts Fitting

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!

Unique Parts

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.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
