I know that thread was locked because it was off topic, but I just wanted to throw in my two cents on Coliseum. Different stores serve different niches. Coliseum doesn't sell semi-auto modern sporting rifles--period, end of story. Even before the unSAFE Act, MSRs were never a significant part of their business. They deal in a lot of hunting rifles, handguns, shotguns and surplus/pre-owned firearms. They also have a lot high end specialty brands that other LGS don't carry--Volquartsen, Tactical Solutions, Kimber. Given their business model, their owners' policy is that no semi-auto rifles are compliant unless they are specifically ok'ed by the state law enforcement agencies. Now, I don't agree with this, but if they are making their money on handguns, shotguns and bolt actions, I can understand why they aren't going to take chances with their FFL's. They will sell semi-auto rifles, but only those models that are specifically on the state's approved list (i.e., sell traditional rimfire rifles, mini-14's and browning BAR hunting rifles, and the kel tec su-16A and B versions). They will not sell or service any AR, AK or the the like. Since they won't sell them, why would you expect they would do a transfer on receiver? If they had a racks of compliant AR's and refused to do a transfer, then I could see getting upset. If it's just a policy of not dealing in MSR's for whatever reason, I could respect their position--even if I don't agree with it.
Putting all that aside, I can still understand someone not being a big fan of Coliseum. Some of the guys there really don't know much about the guns they are selling--even though the pretend they do (although this is a problem with a lot gun salesmen in general). Coliseum's prices are also high on everything--guns, ammo accessories. I have looked at plenty of guns there, but I have found the same guns elsewhere for over much less and even those other places aren't exactly bargain hunters' delights. So, there is good reason to criticize Coliseum, but not because they won't transfer a "compliant" msr.
