It remains cleaner than other gas operating systems, allowing the gas, smoke, and burnt powder to remain in the barrel, which means less maintenance required. With only three main parts, it's one of the simplest, yet one of the strongest, lightweight, and perfectly balanced systems out there.Each of these shotguns undergo individual quaility control tests from Girsan before shipment to insure proper functionality.

My first Girsan purchase. I can't believe how smooth of a gun it is and how comfortable of gun this is. It's a steal at these prices. I now leave my benelli sbe at home and this is my go to gun . Better get em while they are cheap

Received this as a Christmas gift this last year. Been shooting/hunting with it for the last year. Excellent shooting shotgun. Started with 2 3/4 clay loads in cold weather. No problems at all. Cycles nice and not much recoil. Put over 200 shells through it with no problems. Now I have been duck/goose hunting and still no problems. An excellent gun, especially for the price. Also easy to clean. Highly recommend this gun.

Picked up this shot gun from buds to do some upland game bird hutting, dove hunting to be exact. Have to say the price and video buds put out really drew me to the gun. Took it out for the first time opening day 9/1/15 and put about 40 rounds through the gun that morning. I had 1 FTF & 2 FTE. I was running some Winchester 2 3/4 71/2's through it. We came in off the morning shoot and I broke down the gun, cleaned it and oiled it, replaced the modified choke with the Improved Cylinder and gun ran great after that. I knocked down a limit that afternoon . I went out 3 more times and have around 160-180 rounds through the gun now. The weight of the gun is evenly distributed and the rounded top stock never got caught on my clothes. I had one more issue with the gun on my last afternoon hunt, the gun fired and did not eject the shell, the shell stayed in the barrel and the gun fed another shell into the action and jammed the gun. I had to pull the action open, depress the teeth on the bolt to release the live round, let the action close, remove the shell in the magazine tube, make safe then field strip the weapon. I took my pocket knife and popped the shell out of the barrel. Put the weapon back together and shot another limit! Bottom line the Girsan MC312 shot gun is right about middle of the line for me. I will definitely spend some extra money on my next shot gun!

This shotgun is well worth the money I paid for it. It came in a nice carry case, clean, and well manufactured. Easy to assemble. I cleaned and oiled it before shooting, but probably didn't really need it. There are some issues that you might like to be aware of, such as the material of the barrel. The "special steel" seems a little economy. I don't doubt it will handle thousands of rounds, but probably isnt going to last 50 years. There are some protruding, sharp edges in the plastic around the receiver that need filing or sanding down. The lifter is a little tricky and catches your thumb when loading the magazine. The awesome is it eats any ammo, and it loves the cheap stuff. It swings well, very balanced, and shoots straight. Took it through a few rounds of skeet, and it held its own with the thousands of dollars Brownings. One fte in first hundred rounds. Fast cycling though.
