lowers are not caliber specific it looks like an ar 15 pattern lower so anything that is the same length as a 5.56 nato round could work. That said the PRICE IS F ING CRAZY HIGH!!!!!!!!What caliber ? Thanks
Buy one at that price. They are going fast.At a local mom and pop shop , you use to get one for $295 out the door now it is $395 so they are creeping up in price .
Thanks for the heads up ICANHITHIMMAN..
