Welcome,
I just joined yesterday myself.
Owned a couple of AR 10 rifles in the past.have a KAC SR25 now and will be looking to purchase another AR 10 in a carbine patform in the near future.
Just picked up a new KAC SR25 ER rifle and i'm looking to build a second upper with a shorter 14.5 -16
barrel.
Looking for an upper receiver that is compatable with the KAC lower.
