there is a massive difference.
Megan’s will work, they will not fall apart like some imported arms did in the past, but they still use a $0.75 industrial grade rod end with a rubber boot. They are made of mild steel in China and painted.
My arms use QA1 aircraft grade rod ends with a 25,000 lbs load rating, the sleeves are aerospace grade anodized in Ontario by AeroSafe and the sleeves are CNC machined from T6-6061 aluminum also in ontario by CCF.
Forget Battleversion too, it’s either my TC arms or SPL. We both use the same rod ends, seals and adjusters. The only different is where it’s made. I think their’s are made in the US.
There is no comparison actually, they are not even on the same scale
