A Subject Matter Expert Checks In

I don’t think I have to say anything about the now standard  mouth foaming idiocy  that comes from these tragedies.  But I   saw this and thought it too good not to share.

 

“An AR-15 is a semi automatic rifle. It shoots 13.4 bullets per second, 800 rounds per minute. It was created for the purpose of hitting multiple targets in a short amount of time, making it ideal for mass murder. It’s been used in the military to clear out areas in the Middle East for the reason above. Compare it to, say, a Glock 19 (a popular handgun, since you’re confused about it). This gun is small and holds a chamber big enough for 10 rounds of ammo. It is not an automatic or semi-automatic weapon, meaning it takes more time in between shots to be able to shoot again. The Glock 19 shoots less than a single bullet per second. It is used in homicides and burglaries, crimes with singular victims. it is not ideal for mass murder because of its inability to target multiple people at once. But you know what can? A fucking semi-automatic weapon”

 

Video: AK12

This video shows off the AK-15.  The same rifle as the AK-12, but in 7.62×39.  One notable change in the AK-12 and AK-15 over the venerable AK-47/AKM/AK74 is a free floating barrel with the gas tube fixed to the receiver.  It also has a side folding collapsing butt stock.

But the most interesting thing about this video is over at 27 seconds the target they show appears to show key-holing.  This is where the bullet impacts the target sideways.  Not very impressive from any rifle.

M203 Information

I was asked by someone on AR15.com to find some information about the M203.  I am posting it here so it will be available for everyone.

I weight a 9 inch and 12 inch barrel on a precision scale.  Both barrels had grease on them which I did not clean off.  I can’t tell you how much the grease threw off the measurements, but this should still give  you a fair comparison on weights.

The 9 inch barrel is 14.7 oz, or 416.6g.

The 12 inch barrel is 17.54 oz or 497.5g.

It makes me think that since the 12 inch barrel is so close to 500 grams that may have been a target weight for the barrel.  When I first put the 12 inch barrel on the scale it said 500 flat, but when I moved it and wiggled the barrel it ended up settling down to 497.5g.  So in the end, the 9 inch barrel is about .18 pounds lighter than the 12 inch barrel.

LMT M203 with unknown brand 9in 40mm barrel.  LMT Stand Alone Stock, Daniel Defense Front Sight, and unknown rail mount leaf sight.

Also, the Army says that the muzzle velocity of the M320 is 236.22 fps, and the M203 is 250 fps.  But I don’t know what barrel length they are referring to in that.
