Great upgrade, but needs some additional standardization to it - JP Enterprises Gen 2 Silent Captured Buffer Spring System

This was pretty easy to install on the surface, but then the weirdness started. The instructions and videos that I found all contradicted each other. I have a carbine length tube. The inconsistencies were: 1. do you need the detent pin stop or not? I found that it's not necessary, but the official instructions don't say that; however, on the youtube video it says it's better to remove it. 2. The length of the spring system was too short. They include a little 1/32 spacer in case you need it, but mine was easily 1/8" too short (I could not screw the tube in any more without it blocking the upper). The website and instructions actually say not to add additional spacing; however, the youtube video said to put a "quarter" in the back. Well, I ended up cutting a 1/8" washer out of the included nylon spacer, which worked perfectly fine.
