Don't use a sharpie to outline your weapon, the ink will absorb into the cells of the foam and leave an outline after cutting. Instead use a piece of chalk to outline your shotgun, cut out the insert with an electric carving knife, and then wipe the chalk off with a damp cloth.

They're primarily used by corrections and police officers for crowd control and riots. The idea is to gain compliance over any potential bad guys before putting yourself at risk. They could also be used in a situation where there are both good guys and bad guys in the same room - say a family member and an intruder. They're a less lethal option that have a limited, but useful role.

I was wondering if anyone has any experience with Bore Thunder rounds and the M4? (search "bore thunder" on google, I can't post links). They're a diversionary device, much like a flash bang only without the BATF hassles. They produce a rapport of 182 dB, a flash of 6 million candle power, and a pressure wave of 1.5 atmospheres. That's equivalent to the sound of one pound of TNT at 15 feet, and a flash that's brighter than most lighthouses. The intent is to render anyone in a room where it's fired temporarily blind and deaf for up to a half hour. In a home defense situation, their use may result in not having to resort to deadly force to defend one self. The manufacturer (ALS) states that they are not to be used with screw in chokes. I called them and talked to one of their techs, who told me that the problem arises if the diameter of the choke is even slightly less than the bore. The pressure will grab the lip and blow the choke right out the front of the barrel. He also said that even if the choke perfectly matches the diameter of the bore, if it's overtightened the lip will deform slightly, and it will go bye-bye as well. Knowing this, I can be careful about what choke to use. My question is, does anyone have any experience with Bore Thunder rounds used in a Benelli M4, and if so, what choke was used? Thanks much!

When you installed the new bolt release, you inserted the roll pin too far into the receiver, and the bolt carrier is getting stuck on it. Take a flashlight and look inside the receiver at the rail where the roll pin goes. You will see where it is sticking out. Simply punch the pin back down from the top a couple millimeters below the rail and you will be good to go.
