10.5 inches just doesnt give me confidence.
Would give me plenty of confidence for working in porn...:cool:

What was the twist rate of the gun? My understanding is the 1:9 twist works best with the heavier bullets and manufacturers are making the m4 with 1:9 twist, at least for the civi markets. I have heard good things about the 77g out of the M4 length guns, but I don't have any data on it. Will have look around.
I don't want to use a submachine gun I want a rifle, 10.5 inches just doesnt give me confidence.
Also I like bayonets and I want the prick on the other end as far away from me as possible if I were ever to get the chance to stick him.
The SEALs are using the CQBR Mk18 rifle with the 10.5" barrel for VBSS employment. Tight qtr's on ships hulls and door way's.

Trying to determine the twist ratio to ammo type is based of three things.
1. Barrel LANs and groove twist.
2. Bullet weight.
3. Speed of the bullet.
Fast twist = Heaver bullet. Slow twist = Lighter bullet.
The 1 in 9 twist was introduced for civilian market, due to it ability to handle multiple types of bullet weight and bullet punch. The 1 in 7 twist is used by Military market, due to the type of ammo used in the Military. M855(green tip) & M856(tracer) is the changes made in the mid 80’s due to the army wanting longer range and ability to punch thru light armor. The 1 in 7 twist was based on the M856 tracer round, due to a slower rate would not stabilize the bullet in flight. All though the M855 and MK262 Mod1 has better performance with a 1 in 8 twist ratio. The M856 can not stabilize in flight with a 1 in 8, or 1in 9 twist ratio. This is why the military uses a faster twist rate on military weapons. If you look at National Match rifles, you will see a 1 in 7 ¾” to 1 in 8” twist rate. Because the National Match loads, receive better accuracy from these twist rates. 77gr and 80gr…
That's why I was wondering if they were using heavier bullets in some applications (eg, Seals using 77g Black Hills) did they also match them to a faster twist rate. Looks like the answer is no. Do we know if those shorty ARs the Seals have built also follow the standard 1:7?

I would totally disagree.. regardless of the round, you stand a larger chance of impacting a bone and causing significant trauma due to the secondary fragmentation induced into the wound channel and surrounding tissue. Not to mention the fact that there's a lot of significant organs there that are rather important for everything in your body to function... l
A extremity wound is easier to care for and deal with, and significantly more survivable than a round taken to the chest cavity (navel to neck, basically)
Thats what I originally thought too, maybe the medics were bullshitting me.
yep. I think I'm the only medic in 3rd div asking MPs to issue bayonets when we go door-kicking.
Bayonets are a must have IMO.
Stupid not to have them, time and time again they have proved their usefulness.
The new one is pretty good, Made by Solingen.... Issued to all field units:
