ive been trying to pick out a 50 cal rifle but i cannot make up my mind.... does anyone have any feedback on any models? i shoot lefty...

i want to get a 50 cal, mag fed, but i cant decide whether to spend the extra coin and go with the arizona ironworks 50 with 5 rd vertical mag or go the little bit cheaper route and get the safety harbor ultra mag 50 AR15 upper but the mag feeds from the left but is about half the price.....

or does anyone have or seen a used 50 cal for sale?

also, does anyone know the balistics difference inbetween a 50 bmg round with a 22" or 29" barrel?

and finally the last question is where are some good long distance ranges in michigan?

Other than your last question, the rest can be or are answered here.

If you're going to get a .50, go with the longer barrel.  Better ballistics.  Sure you may save weight but it's not like you're going to go on a hike with it.

Heres one in the EE from MI. Dont know the seller.
