Wasn't there a short lived caliber called the .45 Professional? essentially the same thing....IIRC. a .45 caliber round that single stacked in an AR. I remember reading abotu it in a gun mag some years back. I say it'll be a flop. the last one was, as will this. .45 is a good caliber, but in this type of a firearm, there are better options out there. |
+1 Doesn't someone else have a new caliber in this range coming out soon. RRA maybe? The reason the AR and the PC got so popular is that is they are standardized platforms. If the 45 caliber rifle version is ever going make it big there needs to 1 and only one choice. That way you can get barrels, bolts, etc from multiple sources. This proprietary route will lead nowhere. |
| Umm, my opinion... Any new caliber is cool... IT'S SOMETHING NEW! Practicality and usefulness are a different story...but there is definitely something cool about American intuition. You know this was just some guy sitting at home bored, because he had gotten done shooting all his other guns, and he was drinking a beer with his buddy.."HEY LET'S MAKE A .45 AR-15!!" |
IMO it looks like a solution hunting for a problem 
|
| It depends on whether the round will be compatible with currently available .45 pistol bullets. I dont want to pay the price for .458 or .50 slugs if a cartridge can use my stockpile of 230gr 45acp bullets. Considering the cost of bulk bullets you could load it pretty cheap in comparison to the other big bore AR cartridges. If it requires the more expensive bullets then I really dont see much point to it. |
Yes, I believe it is a rare cartridge called the 5.56 x 45mm / .223 Remington

I wasn't being totally serious, but you have to admit that 5.56x45/.223 Remington does seem to work very well in almost all "tactical" scenarios. |
.499 Leitner-Wise |
yes they are coming with the 6.8spc..  Bushmaster 6.8spc |

Damn if the barrel is .45 diameter and the bolt is made to take that type of cartridge I would think it would have been easier to chamber it in .45ACP and make the lower to take either grease gun or thompson mags after all the case head of a .45 ACP cartridge looks angled just like a rifle cartridge and it would be nice to have an AR to go with my 1911...hell Bushmaster should make one of those as well..series 70 of course.

45 ACP does not have enough gas pressure/volume to operate the action of an AR type rifle, but the longer version BM has come up with would. If you want a 45 ACP AR, you should be watching these threads: ar15.com/forums/topic.html?b=3&f=15&t=254991 ar15.com/forums/topic.html?b=3&f=4&t=254380 ar15.com/forums/topic.html?b=3&f=15&t=290223 |
