Nice upgrade, could be better - TANDEMKROSS Spartan Skeletonized Charging Handle

I purchased this in order to get a better grip on the charging handle and it looks fantastic. For that it serves its purpose well. However when charging the bolt, the motion is much rougher than the factory handle. This could be due to a new metal rod that is likely not polished vs a 30+ year old factory rod that is most definitely polished by the spring over time. I suspect the motion will slowly become less gritty the more I cycle the action, as the much harder spring will effectively polish the softer metal of the rod. Tantemkross could use polished rods and potentially eliminate this irritation though it would likely drive the cost up a bit.
