CTM Recoil and Hammer Spring Set — put a tired Hi-Capa back to the way it left the factory. Standard weight, both springs, 4.3 and 5.1.

Springs do not fail, they sag. After a few thousand cycles the recoil spring no longer returns the slide with the authority it had, and the hammer spring no longer strikes the valve as hard, and the gun gets vague in a way that is hard to put your finger on.

This set is the unglamorous fix: a standard-weight recoil spring and a standard-weight hammer spring, both at the original specification. It is a restoration rather than an upgrade, which is why it is worth doing before you start changing anything else.

It covers the Tokyo Marui 5.1 including the Gold Match and Government variants, the 4.3, and aftermarket parts built to the same layout.

Good to know before you buy

Standard weight on purpose. If your slide is heavier than factory, or you are chasing a faster cycle, a rated spring is what you want instead.

Sluggish slide travel, inconsistent gas use and light primary strikes on the valve are the symptoms this set addresses. If the gun is leaking, springs will not help.

While the gun is apart, look at the hammer and sear notches. Spring replacement is the natural moment to catch wear early.

Frequently asked questions

Are these uprated?
No. Both are standard weight, matching the original specification.

Will it fit a 4.3 as well as a 5.1?
Yes, both are listed, and aftermarket parts following the Tokyo Marui layout are covered too.

What does a tired spring feel like?
Sluggish slide return, gas efficiency that has quietly got worse, and sometimes a weak strike on the valve.

Does this fix a leak?
No. A leak is a seal or a valve, and new springs will mask nothing.

Should I grease them?
A light coat of grease or oil on installation is sensible, and it keeps corrosion away.

💡 Titan Forge Airsoft tip: Change both springs together even if only one feels tired. They have done the same number of cycles, and doing one means doing the other in a month. More platform parts in Hi-Capa spares.
