All body armor protection is based on velocity. That velocity depends
on barrel length.

The White House claim that the ammunition for the popular AR-15 rifle should be banned as part of a “common sense” effort to protect police officers’ lives is being derided by police officers themselves as a shameful lie.
White House spokesman Josh Earnest said this week that the .223-caliber M855 ball should be banned because it can penetrate an officer’s soft armor and can be fired not just from sporting rifles but “easily concealable weapons.”

Justification for this action must be based on the assumption that potential criminals wanting to kill an LEO are too stupid to change over to a 3.08 or 30-06 firing Mil-Surp FMJ ammo.
Get ready for some F-Troop conducted False Flag events.
They’re actually 7-10” barrels, under the foregrip, with a 1-2” tip visible. I had a Bushmaster Carbon Fiber S16, new since 2006, and it was fun to shoot. Sold it last all to cousin’s daughter’s husband. Under a full-length coat, it’s a breeze to hide with a shoulder strap. Not so much with a 100rnd BETA Mag...

Or practice a whole lot and go for head shots with just about any caliber bullet they choose. What freakin’ morons. Just ban all ammo and be done with it. That is the plan or at least part of it right?
Interesting. I didn’t know anything about the configuration of the weapons they’re referring to. But a two handed weapon isn’t really a pistol, just a really short rifle. Still concealable, but would never qualify as a “handgun” under Texas law.
It has no stock, and less than 16” barrel, so is classed as a pistol, but can be turned into an SBR (Short Barreled Rifle) with a stock addition. Any pistol grip, stock etc will require an NFA/Class III Tax Stamp. It was a novelty piece, but much sought after/pricey when AR-15s became scarce after Sandy Hook event. It was never a true ‘pistol’; you’re right.
Of course, outliers always exist, Hillary could conceal a Sherman tank in the back of those pant suits.
So, they were lying... liberal elites lying to get what they want. Lying to push an agenda against a constitutional right. What a surprise..../s
Excellent fact based point. Too bad facts don’t play a part in this administrations decisions.
Obama's attempting to use his fake 'concern' for police to steal our constitutional rights. What a jerk.
Not concealable at all.
I’m just as shocked as you to learn that the ever tolerant left wing extremists/socialist/commie self righteous pieces of *%^# would stoop so low as to lie. Or not. It’s SOP for them.
LOL - yes, I understand your surprise...
Recently reviewed stats on 5.56 ammo. In order to generate optimum results, a 20” barrel is the minimum requirement. With most people shooting lesser length barrels, velocity required for penetration (originately considered to be a helmet) is not reached. In my opinion, most shooters of “green tip” ammo purchased it as an alternative to standard loads, not for so called armor piercing ability. This proposal is a back door effort to make 5.56 ammo less available to the public by removing the ability to sell production overruns. As panic buying of green tip ammo took place, there has also been a similar run on standard 55 grain ammo much like we saw in the past. Prices are up and availability down, just what I think this administration wants.
I don’t disagree with you a bit. One good thing, arms and ammo manulfacturers have shown an incredibility to make the small, technical redesigns to the products in order to skirt the laws and regulations the government comes up with. I don’t think it would be difficult to make minor changes to the composition of green tip ammo which would pass the government definitions but retain most of the functionality.
Well fast and furious didn’t work out exactly as planned for them.
Barrel length = Velocity.
The problem with a short barrel is that there is not enough length to the barrel to stabilize the projectile. The heavier the bullet, and M885 is pretty heavy for a .224 bullet, the longer the barrel that is needed. Also it is the twist of the rifling in the barrel, or twist rate. It's kinda hard to get a lot of rifling in a short barrel. I don't think that 62 grain 5.56 would perform well in such a short barrel. On the other hand, drop down to a 30 grain bullet and increase your velocity and you have the magic required for penetration. It all boils down to kinetic energy, KE = 0.5 x m x v^2. There are other factors involved as well, but the bottom line is you can create better penetrating ammo than M885 with a lighter bullet which is easier to stabilize in shorter barrel.
I agree entirely. The point of my post was that if you tried to shoot a .223 round through a snub nose sized handgun the recoil would be incredible, especialy if you tired to do it one handed.
