I don't know what brands some buddys use but the crome tubes look great. They have had no problems with them. The paint on the tubes of my ElectroGlide is in bad shape and I need to do something to them.
Had a browning gold that would not kick out 3" shells.put a sure cycle in and never had any more problems w/ 3" or 3.5's.never shot 2 3/4 shells in it so don't know about that.IMHO well worth the money.
I have two SX-1s with them,on a gas operated gun you will have to make the gas ports bigger.Mine will cycle 7/8 ounce fiocchi shells and 1 1/8 trap shells no problem,one thing the action will close at a high rate of speed and make sure the shell is in the chamber.
...or you can replace the factory spring with a "stiffer" Wolf spring that you can get from Midwayusa.com. Sure Cycles are fantastic, and I have them in all 4 of my 12 gauge Benellis. They have certainly gone up in price the past 5 years, though.
I considered Sure Cycle an ingenious solution to a non-existent problem for my Beretta 303/390s.
I replaced the action springs regularly, used appropriate exhaust springs, opened ports if needed and kept the piston/gas chamber clean with Troy Peak's kit. I figured the engineers at Beretta might be competent to figure out the correct system and all I had to do was minor tuning to my loads and scrupulous cleaning.
