When TX DPS wrote their requirements they just copied the TDP requirements. So it’s as close to TDP as Bushmaster is gonna get.
The TX DPS Carbine requirement is on line if you care to search for it.
If you were to plug the DPS Guns into Rob S.’s chart the DPS gun will check a whole bunch of boxes the commercial Bushmasters don’t. For example the castle nuts are staked not Loctited on, actual 5.56 chambers etc.
