Choosing the right recoil/buffer spring (GBB)

[bananaphone88]

Just posting a quick thread regarding people choosing the right recoil or buffer spring for their needs. I see alot of companies claiming their 150% recoil spring for instance, will "give you more recoil" or "speed up cycle rate" this is only half true. Alot of people are confused about this.

A stiffer spring does NOT give more recoil, it gives you less. As a stiffer spring will absorb more of the blowback momentum making the slide or buffer want to return foreward faster, resulting in less backwards (blowback) force. The effect a stiffer spring will give you is:
Faster cycle rate/rate of fire
Uses more gas
Less blowback recoil

A softer sping WILL give you more recoil, as the spring will absorb less of the blowback force making the buffer or slide go back much harder becouse less momentum is taken away by the spring. In turn a softer spring will use less gas, as it takes less force to fully cycle.
Slower cycle rate/rate of fire
Use less gas
More recoil

Hope this helps anyone out there, ive seen too many people in threads saying they want to buy a 150% recoil spring in theyre gbbp becouse it will give them more recoil. It is the exact opposite!!!!!

Hope I helped some people out.

It gives you harder return to battery, though... this may be where people are mistaking what they are feeling between the recoil portion of the cycle, versus the return stroke.
