Action Army
Code: B06-003
  • For TM M40A5
  • Withstands 500FPS
  • Replaces Worn Sears

An uprated Sear Set for Tokyo Marui M40A5 Bolt Action Sniper Rifles, designed for High Power Builds where the Stock Sear Set won't be able to withstand the pressures. The Sear Set is constructed from Steel, then finished with a Black Coating.

Full description


The Sear set is specifically designed to be used in custom TM M40A5 Sniper Builds where higher power springs are used. Sears are used in Airsoft Sniper Rifles to hold the Piston back when the rifle is cocked, meaning all the pressure from the Spring is held on these small components, in a stock TM Rifle this is fine, as the spring is low powered, but if a higher power spring is used the force can be enough to snap them, meaning a more heavy duty alternative must be used. These sears are specifically designed to withstand those pressure's, leaving lots of room for upgrades, and great for combining with Action Army's other upgrade parts. These Sears are perfect for those Airsoft Skirmishers who are looking to upgrade their Tokyo Marui M40A5 Rifle, and want to push it past the Japan Friendly 350fps, up to UK Site Legal 500fps, with no worry of damage to the rifle from the high power components, or for those who simply want to replace their old or warn out sears.

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.
