That looks like a 22 magazine. Either dedicated upper or 22 conversion in a cut down barrel. Standard mil-spec lower, magpul trigger guard with a tangodown battle grip, and a magpul ctr.

I have a 10.5" 223 pistol and a buddy has an 8.5. Add a 2 chamber brake or a "loudener/flash enhancer" and you really stand out at the range.

I'm building up a 308 lr308 pistol and am currently deciding if I want to do 10.5 or 8.5.

Might as well kiss gun control goodbye. This has been 3D printed:



http://gizmodo.com/the-world-just-got-its-second-all-3d-printed-metal-gun-1651348942

I've known for a while this was possible - NASA printed a rocket thrust nozzle after all. The powder based metal printers (which are just extruding molten metal) are prohibitively expensive for now.

They'll still make laws regulating production of firearms (something the ATF already does. It might stem from the NFA.)

I redid my IWB P290 holster.



The first one had some issues. This one seems pretty much perfect. As concealed as possible, but still gives an uninhibited grasp of its wee little grip. I hid the screws on the bottom edge by folding the kydex over them (the inside around the trigger guard is two layers pressed together) and left a lot more room for the front sight to clear.

Someone had asked about some details. It's pretty straightfoward, and yes, I did elaborate a bit a few pages back when I showed a Crossbreed-style holster I made for a fullsize gun. But I can do a bit of step by step if anyone wishes.

In summary, it's basically-

1) Acquire some leather, some kydex, and a bag of chicago screws.
2) Buy a heat gun from Harbor Freight.
3) Profit.

A dremel is also useful for trimming formed kydex. And a drill, of course, for making holes. I cover the gun with aluminum foil while doing the major heat forming. The rest is not too hard to figure out.

I knew they had been working on metal printers for years, I think DARPA was at least 5 years ago, didn't know it had even gotten that far yet.

The concern isn't a private individual wanting to manufacture and sell firearms. If they go through the normal channels I'm sure that's fine. The "problem" is the ability to easily pass those channels because you're manufacturing at home. IE: felons printing firearms.

There's a legit concern there when a organized crime can stamp out their own burner weapons.

they used a laser sintering printer, no extrusion. the hybrid (welded spray powder additive, milling subtractive) metal printer would probably be better suited to the complex shapes of slides and frames.

I'm sure they will, but said laws won't stop criminals. I see it as one of the potential unexpected consequences of 3D printers: criminals everywhere will eventually simply 3D print their stuff or pay someone to do so, and "3D printed gun" will become the new poster child for gun crime. Then the pointless regulations can fall by the wayside.

I guess I'm not fully up on all the 3D printing tech, but unless you can make something that can handle 50K-65K PSI for more than one shot the actual usability of printed guns is suspect. Of course, when guns are used in crime they are often dumped right after so maybe long term usability for criminals isn't as important. Then again, not even criminals want there gun to blow up in there hands/face.

Pretty sure the barrel isn't printed, just the "gun" parts...basically the frame and slide. You can buy a barrel and the rest of the parts by mail order with no ID

Any recommendations on a set of night sights for a M&P pistol? Also - is that something an idiot (me) could replace on his own or is it better to find a gunsmith to do it? One of the white dots in my current sights is no longer there and wow does it mess with my aim trying to do it with only two dots.


Went to the local range today - they just opened their electronic/virtual target lanes - it's basically a projection over some sort of gel background that registers where your bullet hits. Moving targets like zombies, balloons, shooting gallery, etc. Have to say - I thought it was very gimmicky and rather lame. I didn't trust the hit register at all, and it felt like I was at an arcade (only shooting real bullets). Call me old school, but I think it will be back to paper for me.

Also thought it was ridiculous that I could not shoot my MP5 .22 because "no rifles" but the guy in the lane over was shooting a .22 pistol. Not sure how my MP5 is going to cause any damage.

I put some XS Big Dot night sights on my Walther PPS (easy enough with a hammer and punch). I like them quite a bit. They're not quite as accurate as say a traditional 3-dot system but high precision isn't their purpose; they're (intended to be) quick to pick up. I shoot competitively at my local range once a week and have found they're more accurate than one thinks.

Anyway, I recommend those but they're a two dot system (I got the bigger front sight set) not not regular three dot.

Yeah, did a few searches, they are doing rifled barrels too. Why? Probably because they can.

Yeah and I'd want to see the engineering data that supports the idea that printed barrels can handle 50K-65K PSI. I for one will not be testing that with it in my hand or near my face...

Why? Pressure totally depends on caliber. Their gun is a 1911 in .45 ACP. Max pressure is normally 21k PSI. They haven't elaborated on whether or not they did any proof testing, but even that would only be 25k PSI if they went 20% over.

From what I'm reading they are getting limited number of shots, 50 or less out of them. I want to say I read something recently that was in the thousands of shots range, but I can't find it now.

Infancy tech is in it's infancy.

honestly I may just sell the gun and get something else rather than spend the $100 or so on new sights. Plus it's more fun to look for a new gun (that is not a Glock) than it is to look for night sights.
