The UT guns have been chafing me even more since I've read about the US military's LSAT and CTSAT development programs. These are programs to develop caseless and plastic-cased telescoped ammunition. Instead of a reciprocating bolt carrier, the firearms developed in these programs have rotating chambers where the spent remains of the case are pushed out by the next round of ammunition. This eliminates many failure modes of traditional firearms where cases fail and get stuck or fail to clear the firearm and it reduces felt recoil due to less reciprocating mass. Since the chamber is separate from the barrel, it doesn't retain heat like legacy firearms, so cooking off is not an issue. The program head has stated that a belt-feed mechanism has been designed that can be changed in the same time as a traditional magazine.
Designing a new firearm and ammunition hand in hand with no need to incorporate legacy elements means that bullets with very low drag have been incorporated as standard, allowing a 7mm caliber that delivers the same energy at 1200 meters as 7.62x51 with a lighter bullet and less felt recoil.
None of this is reflected in UltraTech, though.
