The reason I asked was because I bought the Mossy as my starter 3 gun shotgun, and for the most part agree with what has been said about it so far.
The railed fore end is not useful for me, and I have been bitten by the rails when I've been in a hurry. I do like the mag capacity and the price though. The stock? Meh. I could take it or leave it. I do like the sights for slugs. I don't want to put optics on mine and have to run with the Big Dogs. LOL.
Having removable chokes might be useful if I used the shotgun for anything else, but I don't.
Definitely the thing that I have found that has the most impact on my scores is not ####ing up. LOL. Plan out your stage and don't forget to engage any targets. That really flusters me and throws me off. The next thing would be to practice loading the shotgun and mag changes on the AR.
I only did a couple matches last year, but plan to do more this year. I'll probably change my kit at some point in time this year when it comes to ammo storage and might change out the shotgun next year.
Too much fun! Talking about it is getting me antsy to go again!
