Hey guys, I have been reading this forum for a long time, and I know there is generally no love for the piston system in ARs, however, I recently acquired a SR556. I have a few DI rifles now, (DD V5, V9, 6920) and I have been thinking about keeping the Ruger around just to mess with. I know almost nothing about piston AR rifles, but my total investment into this rifle is so low, I am tempted to put a little more into it and see how well i can get it to run.
So my question is, what are some recommended part upgrades for piston rifles? I know there are some things you can do to the DI system to make it more reliable, is there anything I need to do for this type of rifle?
Any input is appreciated, I have thought about selling the rifle, but the piston system kind of interesting to me right now, and I have almost no investment into this rifle so if I decide to sell it down the road I won't lose much if anything.
I should probably mention, that my intended use would be as a general purpose scoped varmint rifle for around the house.
Thanks in advance.
