.45acp Olympic Arms Upper

[imschur]

Fedex dropped off my .45acp Olympic Arms Upper. I was pretty surprised that given the state of the gun industry I took delivery in less than a month. I am quite shocked at how light the upper is with that big .45acp bore.  I chose the proprietary OA 18 round capacity magazine option as to not alter the lower reciever. The setup is pretty unique and I will try to get some pictures by next weekend. I have a YHM .45 QD Wraith Sound Suppressor on order to mate up with it but I doubt I will see it in 2012.

That sounds like it's going to make a fine CQB carbine.

That sounds pretty cool. I have 3 questions.

Will you have to modify the lower to use with this upper?

How much does the 16" barrel increse the muzzle velocity.45acp round?

Is it capable of shooting any type of .45 bullet?

no modification or magwell inserts thats why I chose the proprietary magazines.

I will only be using AE 230 grain ball ammo if it functions properly. No chance of the round going supersonic

I have some Federal 230gr Hy Shock's (Federal 45D) that I will try just to try. Those are the only two types I shoot in bulk.
