So the newer op rod is shorter on the sliver part?
You are correct, the piston is shorter.
Nice feed what is your cleaning regiment on you xcr since your using all corrosive looks like it's holding up great I'm at 1500 on my .556 xcr and have had zero flaws they are great rifles
Cleaning regiment:
In the house, straight to the sink.
I pull the upper, muzzle in the drain, spray hot water down the barrel and gas tube, spray around gas block and break. I run more hot water over the op rod and gas adjuster.
The upper rests muzzle up and I spray G96 around the break, down the barrel and gas tube. Patch, patch, patch....done. My system gets it done in under 10 minutes.
I'll mention that this isn't my cleaning regiment, this is corrosion prevention. When I actually clean it, I just add elbow grease to the above.
Fwiw, I'm at 5200+ rounds now. I didn't shoot much during deer season.
Thanks all.
Just for fun
