Belt Fed Info

I've been thinking about picking up a belt fed rifle. I've looked at the Valkyrie Armament BSR rifles and also the Ares Defense Shrike AMG. I'm sure someone has posted on these but I couldn't dig it up. I feel that the Ares Shrike would be a better purchase , however I have not handled either one. I am leaning toward the shrike because of the ease of changing from linked ammunition to mag fed without making any changes to the rifle at all. With the Valkyrie BSR you have to pull the rear take down pin on the lower receiver and pull the belt fed mechanism out before it will feed a magazine. With Valkyrie you have to either send your lower to them to make changes to it or buy their lower receiver. With the shrike, no changes need to be made to your lower receiver nor do you need to purchase theirs. I don't feel like a full auto rifle is necessary (for me) but the tac-con 3MR trigger will probably be in it for sh#ts and giggles. The Shrike has a quick change barrel system and that I like though not necessary if the rifle isn't fully automatic. Then again, why own a BFR that's not. I like that the Ares is piston driven not gas impingement as well. I'm just talking it through my head (though I think I've made my choice) and I thought I'd see if anyone else may own either and see if they had any input. Thanks in advance.
