300, they are hard to find at a decent price, I had an 1187 with one on it stolen last year, everything was Mossy Oak camo on it, killed one turkey with the scope, used my backup the rest of the year, got me another 1187 , this one has a short barrel on it, it is at the shop right now getting drilled & tapped, I got lucky and found one on craigs list for $160 shipped, it is como'd too, bid on one on ebay to $185, good luck on finding one
