Ruger sr556

My personal opinion.....stay away from any AR with propreitary parts....something breaks on a mil-standard AR, there are 100 shops selling parts. Something proprietary breaks on the Ruger and you will be out of commision for a long time.
 
I'm looking at the SR556 FB standard AR. The piston system, BCG is proprietary. So is the handguard, it's pinned and not supposed to be removed. Basically, I think all piston AR's have a proprietary gas piston system.

Curious to know how just how many piston rifles has failed so far for you guys to dislike them?

Its more like a solution to a problem that doesn't exist, which creates its own set of unique problems.
Proprietary parts for one thing, which Ruger will not sell you to have spares on hand, have to send it in to them. And yes, the bolt carrier design already has changed since 2009 as it was creating excessive wear due to tilt. Will they even still be making these in 10 years? Who would want something you can't easily get parts for?
Piston going to be more reliable? Not likely in any real life scenario, plus more parts to break down and clean, and lose.....back to availability of parts again. And Ruger casts everything they can, which also weakens the design.
Piston will affect accuracy, how much....I dunno, but the DI is one of the reasons the ARF is so accurate. So again you are giving up accuracy for nothing.
Front heavy, can't change that, can't swap out parts or barrels down the road, not modular anymore, big drawback.
 
I like mine. I haven't shot it enough to get more than first impressions. It is well-built, on the heavy side, but it sure runs clean! The purchase through Irunguns was smooth, with no delays or surprises.
