I’m very disappointed with the Mossberg SA-20 defense. Nightmare to disassemble and reassemble. Everything was way too tight. Won’t cycle Buckshot. For sure not clay bird ammo. Jon Tatum’s Mossy Oak Video makes it look easy as my 870 REM to take apart or my 11-87 REM automatic. Hang on OK

Had trouble reattaching barrel to gun. Overall a very stiff gun, hard to load and action is very tight. Will not eject regular clay loads, works fine with higher priced rounds. Hope it breaks in over time and use.

I've had this gun a couple of years, but have not shot it a lot. Primarily a home defense firearm. Whenever I have shot it, it worked flawlessly. For home defense, I personally feel 20 gauge is plenty. It will mess up the target at home defense distances. (By the way, it is silly to give it a poor rating because you don't have ammo for it. Jeez, really?)

I bought this for my wife on her 40th birthday. This is an awesome gun for beginners.

It's a Mossberg. Perfect home defense option for my wife. Bud's made painless to purchase and shop to a dealer near. Thank you.

The gun looks nice but until the ammo that I ordered for Buds arrives I cannot use or rate the gun!!
The star rating will likely change when I can teat the gun

Nice look and feel ,I like the sight . My first time out I tried shooting 7/8 ounce target loads .The first 50 rounds gun would not cycle at all.By the end of 100 rounds I could sometimes get it cycle 2 or maybe 3.My inspection of gun before my first time out was good.Gun was clean no heavy grease etc. I did use a little oil because action was really tight I felt.After first time out I did complete disassemble and clean.Everything looked pretty good and still feels nice and TIGHT. Second time out I picked up 2 boxes of 1oz game loads and grabbed 2 more boxes out of my case that I tried the first time.The 1oz loads worked much better and by the time I got to the 7/8 oz loads they were working better also. I still cant depend on it to cycle 100 percent of the time but its gotten much better . Probably 80 percent of the time. I bought a case of 1 oz heavy loads .The action still feels really tight in my opinion .I do like this shotgun , Im gonna clean it up again , take my case of 1oz loads out and give it hell to loosen things up and repeat as needed until Im confident in 100 percent cycle

Great service from Bud's. I decided to trade in my Remington semi-auto 12 gauge as I have rotator cuff problems at age 76. I opted for a Mossberg 20 gauge semi-auto tactical for home defense. All went well and I picked up the Mossberg at my FFL, and it is a beauty. Later on the computer I discovered Bud's had reduced the price by $20. I looked into the Norton guarantee to refund any price reduction during a 30 day period. Norton wanted a screen shot of the reduced price prior to refunding the cost difference. When I attempted to do this, Bud's had changed the price back to what they charged me. Norton said they couldn't help me without the screen shot, but they would accept an email from Bud's stating the price reduction and increase. I called and emailed Bud's and they took care of it and sent me an email that Norton would send a check ASAP. Within 3 days I received a check for the $20 price difference. Great job Bud's!

Great shotgun from Mossberg, fantastic service from Buds (as usual). Two things: 1) Make sure you clean this before you take it to the range the first time. Mine came packed with grease to prevent rust and buildup in transit. 2) Make sure you're using the correct ammo. It needs 15/16th oz shells to cycle properly. I opted for 1oz AA shells and haven't had any problems since cleaning and oiling. Definitely a good alternative to a 12GA in terms of home defense and plain old shotgun fun.

I am extremely satisfied with my purchase from Bud's. I shopped around to find the Mossberg SA-20 locally, but had no success. Bud's Guns made my purchase extremely easy. The initial online chat was very helpful, as well as FAQ's, which led to my decision to place an order. While online ordering was an option, I elected to place my order direct. The customer service associate who assisted with placing my order was great. The shotgun arrived at my local FFL dealer on time, and in factory new condition exactly as promised. I would gladly recommend Bud's to my friends.
