AR-15 with 5.7 Upper
« on: January 14, 2010, 04:39:00 PM »
I sold my 10FP after shooting a friends PS90. I loved the round but wanted an AR styled rifle to change barrels when needed. Am I able to swap the bolt face on a .223 set up to fire the 7.62X39 or do I have to swap the bolt carrier, buffer and spring as well? Has anyone had any issues with the 5.7 upper swap? What optics do you use with the 5.7 upper? :-\

should be just the bolt. I looked at mine and the carriers look the same
