WTS- Midwest Industries carbine drop in quad rail
 

Currently have this on an Adams Arms piston upper a friend and I just slapped together, but got a steal on a used 9.5 FSP rail, so this little guy needs to go to a good home. These are in my opinion the best drop in quad rails and they work great for the piston guys as well.

$100 shipped takes it or local face to face in San Diego for $90.

PM or email.

Can you post a picture or two? Thanks...
