X-Force 1.5 Upgraded Spring for M24 Metal bolt V2
This is a top grade spring made of silicon-steel which is extremely durable and hold their shape for much longer than standard steel springs.
We have tested this in the metal bolt kit V2 and it increases power and was shooting over 400 fps.
Length: 22.5 mm long x 12 mm od x 9 mm id
NOTE: These will not work in standard kits and will cause damage to your blaster. Do not install in anything else other than the m24 metal bolt v2 kit.
