I agree that they are not the exact guns but unless they are trying to get any club approval for accuracy the toy could work for them to use, but that was not stated.
As Stormtrooperguy and Fett4Real stated, that Hasbro thing is no where near a base for a Rex or any other commander pistol, for club approval(s) or not.

i've seen people here upgrade parts on their suits because of a millimeter difference in the diameter of their gauntlet darts.

i'd say the best bet for rex pistols is to either scratch build or buy a resin set. if the latter, just make sure to sort out whether you want real world style or animated style, since they are pretty radically different.
