I think what we have to keep in mind is that everyone in the biz has either a dog in this fight or wants to enter one. It is for this reason that USASOC has been extremely "proprietary" about the 6.8mm SCAR round. What I am most often quoted by officials at both USASOC and USSOCOM is that they "don't want to get inundated with unsolicited proposals" (e.g. USP in USSOCOM acquisition parlance). Therein lies the rub -- allegedly. There is a fundemental fear that any one of a number of weapons designers having pockets of any depth, will get the ear of one or more members of Congress and thus put pressure on the Command. Having said that, I suspect that certain favored vendors (we know who they are) are already working the issue with the commands at Bragg and MacDill to ensure their products most closely align with the soon-to-be-released JORD for the SCAR.
The upshot of this situation 6.8mm is the proverbial Hobson's Choice. Simply put, better mousetraps come from industry -- not governments. In my experience, the folks at Picatinny and Crane are interested in milking projects for as long as they can, while stealing the ideas of entrepreneuers and then placing them into production. Mike Rock, LMT, GEMTECH, KAC and Smith Enterprise are some of the victims that come to mind. What is needed is more light on the subject and a release of the TDP on the new round. When this happens, a thousand ideas will bloom, to borrow a phrase. It will not take Colt, HK/ATK or FN to develop a winning formula. Perhaps that is the problem from certain perspectives.
As to the round itself, Remington, which has already produced 100K 6.8mm rounds for RDT&E, will do nothing to risk losing any potential forthcoming contract.
In sum: be patient or just work on your HUMINT skills.
