JP Enterprises Silent Capture Spring

[Michael]

Standard AR15 recoil springs need to be replaced periodically as well. It was one of the main things we had to check when doing PMCS on weapons in the Army, although many people with military service won't recall this because very few units actually follow the PMCS by the book. For those that did, just mentioning PMCS will cause many to withdraw into a catatonic state.

Um...Uh...guess it is true. Catatonia reached.

In all seriousness, all of the springs fail…magazine, buffer, extractor...even the ejection port cover spring. I keep shot-logs for most of my weapons (not super anal, +/- 100 rds or so) and when they hit 1000- round increments, I do a detailed check of all parts, paying particular attention to spring tension and length. When in doubt, I replace.
