Ohhhhh! This Gas Piston will make your AR AWESOME!
Problem is, some people consider JUNK as top shelf. I consider NiB junk because my experience tells me its junk.
Some people consider Nitrided barrels an improvement. I say most of them are inferior because they are treated after the BBL Extension is installed.
Some people consider 1 piece Gas Rings an improvement. I know they are junk.
Some people think certain Rail Systems are improvement. I think many are far from it.
Some people say that drop in triggers (pack triggers) are an improvement. My experience tells me that Factory FCG's, Geissele, and LaRue are the ones that work the most consistently and safely.
Agreed on all counts. I'm a firm believer in not trying to fix what's not broken. Just improvements where prudent for better functionality, reliability, or ergonomics. No changes just for the halibut.
