Customer Comments & Questions

Customer Reviews

(5 out of 5) You need to clean before using the first few times
by Chris from Victoria, MN on January 28, 2022

When I first took this gun out I couldn’t get it to cycle. It would fire fine, but it would not seat the next round. After taking the thing home I cleaned off all of the machine oil and let’s just say I exaggerated with the CLP. After bringing it back out it worked great. It’s also extremely important to take note of the type of round you’re using and the FPS. 1600 FPS or less is better for the lighter gas cylinder 1600 or more you’re definitely going to want to run the heavier one. I took this out hunting this year as well and although I wasn’t skilled enough to shoot a deer this year, at the very end of the trip I shot a knot on an oak tree about 70 yards out like I was 5 ft away.

(1 out of 5) Will not cycle
by Richard from New Braunfels, TX on August 6, 2022

I fired 200 rounds and it would not cycle properly. Shells continued to get stuck and failed to eject properly. Fired after clearing the chamber each time.

(5 out of 5) Boss 25 12 Guage
by Antonio from Peoria, AZ on July 31, 2023

Very pleased with the service and timely shipping. A good friend suggested your site. I have previously made purchases of rifles and ammo from Guns.com. Sportsman's Outdoor Superstore is a great website with excellent prices!

(5 out of 5) Boss 25
by Rick from Dittmer, MO on August 31, 2024

Plain and simple. Shot it and bought two more. Three in just a couple weeks should say it all. So much fun for the money. One of them I plan on raffling off for my buddy who has cancer.

(4 out of 5) Recoil sensitive
by David from Sanderson, FL on February 3, 2025

The Boss 25 likes to shake loose from recoil. All the threaded parts, muzzle guard, pressure port, barrel, and butt stock keep coming undone and need retightening. As long as you are aware of that and check it often, it shoots just great. Nice semi auto.

(2 out of 5) Dont Reject the Hulls
by Michael from Monticello, KY on July 15, 2025

I bought the Boss 25 in Dec. and still today haven’t got to shoot a clip full out of it. Anyone out there got any solution on how to fix it, or can I get a replacement for it?

by joe d acosta from San Antonio, TX on August 15, 2025

Handles really good, and I have enjoyed firing it.
