JP Enterprises Silent Capture Spring

[GMinor]

Easy to set up an automated machine to repeatedly compress a spring similar to the environment the spring would see in the rifle. Run the test through an environmental chamber at the same time to simulate temperature variations (seasons) throughout the year and you have a reasonable test that is repeatable giving you the data to average out the 500k round claim. This is a standard industry practice to extrapolate expected lifetime of any product.

Yes, bwaites, be realistic.

Easy enough to set up a machine that stresses the spring 500,000 times, let that pig run for a few days or weeks and bam. You have 500,000 compression cycles.
