Great worked as expected. BCM is fast at shipping too.
As advertised! Works perfect
It's a spring, makes a little noise but that's expected
Don’t know why but the BCM spring seems to make less noise and seems to shoot softer. Don’t know if it’s just me or the tubes that come from BCM but I just like these the best.
Seems like a good spring, the finish on it isnt great, but no one is going to see that anyway.
Does the job, better than budget brand springs.
