I will disagree with you (somewhat) here. A gas piston AR shines when running suppressed, used in an SBR, or if you're going to run the gun HARD.Some things to be wary of: Pistons. Are they good or better than the AR system? Who knows, everyone (and this is important...when I say that that means it will be on the test later). yes everyone has their OWN piston design. How many of these companies will be around in 10 years? Are they proven?

What I am say is this. Millions of M 16 across the world us the GIS and its worked and worked rather well for 50 years.LebbenB wrote:

As to each gas piston design being proprietary, I will agree with you here. But the same can be said of any .308 AR - there's no particular standard that a gun maker has to meet (The de facto standard is the SR25/M110 due to it's use by the US Army), but that doesn't necessarily mean that the gun maker is producing an inferior rifle. Armalite, for example, uses 4140 CMV steel for it's barrels. The standard (Known as a Technical Data Package or TDP) for an M4 is 4150 CMV. Does that mean an Armalite barrel is vastly inferior to an LMT barrel, which uses 4150 CMV? Not at all.
A piston AR made by a reputable company such as HK, LWRCi, POF, or Adam's Arms is as durable as it's DI counterpart. In a lot of cases, these small piston companies are pushing the envelope in materials and coatings used in building AR's versus slavishly following a standard set 60 years ago. I have no doubt that when my son is my age, he'll be able to find replacement parts for Dad's old REPR.

You bring up the core issue.Siscowet wrote: :usa: This is why I like this forum. Knowledgeable experienced guys talking about my favorite rifle. They both know more than me so I am not going to get in the middle of it. There are a lot of reliable gas piston products out there, had one myself long ago, bit the GIP works well also. Just a note, the gas piston SIG 516 has been reported to have issues with M193 5.56 ball, that appears to be a design issue in that it was optimized for M855 ball pressure curve. Off thread, not 7.62, but the point is any design has to prove itself in the real world of sand and mud before it passes muster, like the AR and AK's have.
