I acquired this Boss 25 from sportsmans guide for just over 500.
2 5 round steel magazines with polymer followers
5 chokes with the modified also being a muzzle brake.
A tool for changing chokes
A heavy piston for loads over 1500 FPS
Weight is approx 8 lbs
The Boss 25 is a 12 gauge semi auto box fed shotgun. It has AR style magazine and bolt release levers along with an AR style safety selector switch. The gas system is a gas piston system with interchangeable pistons for both heavy and light loads.
The front hand guard is very comfortable and made out of aluminum. It has short picatinny rails on top of the receiver, front and back top of the handguard and bottom front of hand guard.
It also comes equipped with mag pul style polymer flip up sights that seem adequate although I did attach a red dot sight I had laying around.
The length of pull on the stock is not adjustable but the comb is. From what I can tell it is not possible to change the stock. This isn’t a huge deal for me as it is comfortable. The pistol grip maybe changeable with another AR style pistol grip, but I have yet to test this out.
The 2 5 round magazines that come with the Boss 25 seem well made and are easy to load. They both seem to feed reliably. I have read that they are mka 1919 magazines but have not been able to aquire any to test this out. LSI also sells 10 round magazines but I have not been able to locate any. Magazines do not drop free but are not hard to pull out or insert.
The upper receiver is aluminum while the bottom is a thick polymer, this I did not know when I ordered it. It seems durable enough but only time will tell.
Trigger pull is very nice in my opinion, about 5 lbs, smooth with a short reset.
First thing I did when I got the Boss 25 home was tear it down and clean the shipping oil off of it. This is not a firearm to be field stripped. It requires taking off muzzle break, barrel shroud, handguard that is held on by 2 Allen keys, removal of the gas piston, bolt handle, and then the barrel and bolt. The bolt handle is held in place by a ball detent and it had to wrap it in a towel and use pliers to remove it. There does not seem to be a way to remove the upper and lower receivers from each other without removing a bolt and nut and 2 c clips on pins.
The whole shotgun was covered in oil. I used some break clean applied to a rag to wipe all the oil off I could. I then applied a thin layer of Hoppes elite gun oil with Teflon to all moving parts, then reassembled the shotgun.
Shooting the Boss 25 was comfortable with the expected recoil from a 12 gauge. Magazines fed reliably and I had no FTE or FTF. I fed it mix of; Winchester AA super sport clay, 2 3/4" 1350 fps 1oz 7 1/2 shot,
Kent all purpose steel 3" 1400 fps 1 1/4 charge 4 shot,
Winchester brown box 9 pellet 00 buck,
Estate 2 3/4" 9 pellet 00 buck 1325 fps.
These rounds were a mix of “low” and “high” brass. The Boss 25 had zero difficulty either feeding or ejecting anything i fed it. I am trying to get some low recoil 00 buck to see how it would handle it.
I am planning a skeet shooting day with some friends here soon to put some more rounds through it and see how the polymer lower receiver holds up.
