| I currently have a Bushmaster xm15 e2s with a A2/carry handle upper receiver. I want to switch to the Flattop upper reciever so i can mount my Aimpoint comp2 and x3 magnifier. any suggestions of which manufactorer i should go with??? would it be best to get Bushmaster's flattop at $190 to eliminate the chances of it not aligning with my bushy lower? or is the alignment issue even a concern going between two different manufactorers? |
