I just purchased a RRA NM lower and RRA 16" Varmint upper.

Was wondering what other caliber uppers I can get for this lower.

Alexander Arms makes the genghis and Beowulf uppers. Olympic makes some of the pistol Calibers

That 440 Corbon looks impressive. What are your guys' opinions on this upper? Thanks

I am not sure if there is anyone on the board that ever bought a 440 CorBon. Only about 6 or 7 have ever been made. The 440 was the very first Tromix Sledgehammer introduced, and I actually made two of them a year or so before founding Tromix Corp in 1999. Myself and a good freind of mine used them for hog hunting with great successs. It will launch a 180gr bullet at 2300fps, 240's at 2050fps and 300's at 1800fps. It is very mild recoiling compared to the 50AE, 458 SOCOM, or 475 TREMOR. It's really a sleeper in the Tromix line up. Tony Rumore Tromix Corp
