Whoever designed that doesn't understand the concept of stand-off when using a projectile launcher to bust locks and/or hinges.
Do yourself a favor... don't do any breaching with it...

Looks pretty cool, kinda like a big Phantom 5c2.
. You need a couple of inches of free space between the muzzle and the door to allow this back-splatter someplace to go.
The first shotgun I ever saw that was converted to a breacher was an Ithaca 37 used by LAPD SWAT. It featured the bottom half of the barrel, from the muzzle back a few inches, removed entirely. The remaining top half served as the stand-off. It worked (and works) like a champ.

oh , my bad . I thought you were saying that 2 inchs was needed for the shot load to totally clear the muzzel prior to it's impact with the target area . That's what I was measuring .No, it doesn't... unless you hold the end two inches from your target area. If the muzzle is held against the target area- which we found, as stated, to be best- those scallops provide a couple of millimeters of stand-off at most.
Again... the amount and type of back-splatter depends on the material/construction of the door. I didn't say this thing was totally useless... but after having seen dozens of shotgun breaches (and done a few myself) on various types of doors, _I_ would not use this for that purpose unless I had no other choice.
Expert? No; but I have seen/done more than my share of mechanical breaches. Take that for what it is worth to you.

If you're referring to the FBI's "solution" for the St. Martin prison barricade deal... how could I???
You do know they actually tried it after the deal was over; the jail was totally trashed, and the sheriff said we could finish the job by testing our respective procedures.
The HRT guys got about six inches through that glass before the chicken wire totally bound up the saw.... like Chris told them would happen.
Glad to hear you don't plan to go "operational"... you're like me, too long in the tooth for that sort of thing any more.

How hard is it to add a charging handle like the one shown?
How much to do a Saiga 12 like this Will minus the tax stamp.
