M140 spring for Marui AWS and Well MB44xx

Steel spring for Tokyo Marui AWS and Well MB44xx sniper rifles.

It is designed for original pistons, because its outer diameter is 10,5 mm (inner diameter is about 7 mm). Spring strength during tests in unmodified rifle corresponds to about M140. However, the resulting muzzle velocity depends on the sealing of the gun. The spring has a blackened finish.

Not suitable for VSR series rifles or MB02, MB03 etc. Also not suitable for M24, MB01/04/08 etc.
