@@Rudyelf1 Nice. I chose the rattler because I already have an 11.5 5.56 upper. The 9” is so close to the 11.5 it would almost be like the same gun so I wanted the shortest package possible and went with the rattler lt. I’ve thought about almost getting the original rattle because it’s shorter but I’ve heard that it has key holing issues (rounds turning sideways), I think they fixed that on the rattler lt. Ive also been having some problems with my geissele Ssa-e trigger when running this upper. Might have to get an sig trigger but you may not have that problem. If you’re trying to get the most distance out of your upper using supers and you don’t already have a shorter 556 then the 9” might make more sense for you. 10.3 and 11.5 556s are common and if you want to build one of those in the future or depending on your use case then I’d recommend the rattler. To be honest, I wish I would’ve gotten the whole rattler lt firearm with the sig lower because having this trigger problem is really upsetting. I might swap this lower out for a 10.3 build and try to get the sig lower in the future for the rattler.
