I keep finding more reasons to stick with the Sig SB15 versus going the SBR route. Initially it was avoiding the long approval wait and staying off the first-to-confiscate list. Then I thought how great to be able to say “Sure bro, you can borrow it for the weekend.” And no “Please, Nanny, may I cross state lines with my own damn gun?”
Now the latest reason pictured below.
Why?
For middle of the night HD use. Simplifies and speeds up the process for a foggy mind to react. Namely, eliminating the step of locating and stowing a spare mag. I don’t like the idea of an extra mag attached to the receiver or another mag. Either degrades handling and increases risk of entanglement indoors. Balance actually feels better with mag in back.
How.
Velcro straps are tightened over gunsock after mag is inserted. Tight enough to need decent force to pull mag out. Mag just inside rim of brace to avoid damage/noise. A quick push from the closed end pokes mag out enough to grip. Thirty rounder interferes with grip hand. Twenty works nicely.
Laugh if you must. I did. It is one butt-ugly set-up, but the utility is beautiful. I just started looking for the right shaped leather or neoprene sleeve to line with gun sock. I need a name for the concept appropriate for mag insertion method and location that is not too crude. Butt-Load already ruled out.
So you didn’t bother to search the SB15? You think Sig is selling something illegal? Read the letter from the ATF giving their blessing for this device. Theirs is the only opinion that matters.
The ATF ruled on the SB15 by itself. They did not rule on an SB15 modified with some cloth and magazine. Do whatever you want, I guess, but don’t make unwarranted assumptions.
Thanks. That is a reasonable observation. But I don’t see how it could be called a modification into anything illegal. It does not make it function as a stock any better than already existed. It can still be fired as any regular AR pistol. And using an existing cavity for storage isn’t verboten. Yet.
It still functions as an arm brace exactly as before. You must open the straps to place on arm in which vase the mag/rag falls out. Intended use is not affected.
If you could be a little specific on how I have done anything that might be construed as making a pistol into something requiring registration, I would really like to know. The legal definitions of pistol, long gun and short barrel are not that complicated.
The ATF didn’t rule on whether I can mount a stuffed squirrel to the FSB either.So what? Cite a potential concrete violation. I would be grateful to hear something I have not thought of and avoid any legal problems. The amorphous fears I’ve heard so far are not an an argument.
