I'm not sure for that particular gun, but look for something similar on www.gunbroker.com
If only in 'fair' condition, around $200-$250. sales@countrygunsmith.net
Depends on year of manufacture, condition, quality of stock, but probably in the ballpark of $400-$500 for a good condition weapon.
Yes, but, expect to pay for it.
Yes, some of the remington tubes will but not all. I have a remington modified choke in my mp 153 right now.
Yes
Is it a screw in choke?
Around $1200-$1500 in excellent condition.
They usually use a modified (medium) choke on the 870, unless it has choke tubes.
10000
It says it on the barrel, otherwise if there's no riffling it's been modified or shot out, but quite unlikely.
Yes but it shoots them terrible. I have one myself and I bought the Remington rifled choke tube and it helped dramatically. All Remington chokes fit the Charles Daly shotguns for your future reference. I also found that it shot the Remington Buck Hammer slugs the best.
The 1187 is a safety modified Reminton 1100. The safety was changed in 1987, hence the model number change from 1100 to 1187.
