Arms Tech Recon Rifle is a Dissipator config.  Majority of sales are FMS if I'm not mistaken.  Not sure if any are in service with US forces.

Yeah... so, when someone burns their hand on their exposed barrel, something that helps to prevent that is fixing a non-existant problem?

The increased site radius is nice too... though, personally, I need smaller apertures for my rear site.

Probably because the idea of a second non functional gas block is lame, as is spending all the extra money for an additional low profile gas block.

I love Dissy's, but unless you're free floating and building from scratch, I think they aren't that logical.

DPMS has a version that elimanates the second, non fucntional gas block.

the down side to the design is that it is still a very heavy barrel.

You only need one gas block.  When you have a rail (and I'm not gonna discuss why they use them AGAIN) you don't need a second gas block.

Why all the hang up with heavy barrels?  Who says you can't have a lightweight/Gov't profile undernear.  And if it were a mass produced item, it wouldn't be an issue to enlarge the gasport to be able to use a rifle length gas system.  Maybe I'm missing something.

You've got the right idea but believe it or not, its not really that big of an issue...not enough for the government to start pouring cash into fixing it. I've been doing the soldier thing for quite a while now and the only thing that ever burned me(besides the occasional jack-ass leader) was a Gortex jacket sleeve full of hot brass and links from my SAW while doing a convoy live-fire exersise.

I didn't throw the question out with a pro or con perspective, just wondering, however I KNOW this:
I can shoot more accurately with the longer sight radius (and you can too).
I prefer a shorter stick for handiness sake (and you do too).

Well many of you, I'd bet.

16" barrels are getting a lot of attention really, with the mid-length gas system they are an excellent choice for a service rifle -- Also, the rifle length gas system on a 16" barrel has been looked at and is not reliable enough for a service rifle, this has been beat to death on here, but time does not alter the truth.

I think a more logical question would be "Why no mid lengths seen in service".

I'm a mid length Dissy fan, and I'll probably never own a carbine or rifle length gas system on a 16" barrel.

Nope, I can put whatever size I want legally on an M16 and I find
the 16" is the sweet spot in terms of length.  Of course YMMV.

What I am trying to say is the 16" bbl wouldn't be nowhere near as popular if there wasn't the NFA.

The reason why 16" is choosen is because there has been 30 years of study and use on it.  If there wasn't the NFA, Colt would have never came out with a 16" bbl SP1 carbine, it would have had a 14.5" bbl like the Colt 653 carbine.  Every Colt carbine would have a 14.5" bbl.  Nobody would know what a 16" carbine barrel is.

Your rational is flawed.  You are assuming a lot by making this statement.  Lets assume there was no NFA law.  A 20 inch barrel allows the M855 round to fragment as desired.  However the 14.5 inch (arguably) does not, or at least not as well.

You really think in 30 years no one would have tried to solve this by increasing the length of the 14.5 barrel but not as long as the 20 inch barrel?

I think innovation would have come along and you would have had an intermediate barrel.  I mean you even have 18 inch barrels now because its between a 16 and a 20 and that has nothing to do with the NFA laws.

I believe it's against the Geneva Convention to induce such heavy laughing into the enemy that it distracts them from fighting, the sight of such ugly rifles in US troups hands would induce such laughing.



For all the times I have disagreed with one of your posts over the past three years, this one makes up for most of them.

+1,000,000


BTW... but I gotta agree with the poster who mentions longer sight radius as a big plus. People get hung-up on the possible accuracy and/or velocity differences between 16" and 20" barrels, but the extra sight-radius would make much more of a difference than those 4" of barrel to most shooters (obviously, if optics weren't considered).

Depends on which barrel you use.  Reliability would be my first issue with the type I like, which is a rifle length barrel chopped.  My last one ran 99% on 99% of the ammo fed to it.  That 1% is huge in certain circles, but I was happy with it, it being my first chopped barrel project.

Not that you've worried about it Mongo, but the chopped barrel upper I bought from you is still batting 1.000 after about 800 rds.

I know with the ones that we made back in the late 80s, we had to open the gas ports to get them to run. But during filed testing they were determined to be not reliable enough for a serice rifle. I am sure that it works fine for what you are doing, but for a military rifle the reliability is an issue.

Also, as I have said many times, opening the gas port is a solution for the port being in the wrong place -- treating the symptom, not the problem.

Maybe try taking it to someplace really cold and see how it works? All the desing work we do is tested at 10 deg(f) and you would be surprised what a difference that makes...



Same problem that CQB-R's have.  A suppressor would be the only help, short of moving the gas port.

Did you notice the sling isn't over his shoulder?  This is one sharp cookie, so he must be "special".

It's plain to see how this unslung mode of carry can avoid a tragic situation.  For example, just when you think you've dropped your weapon and raised your arms in the French salute, the weapon didn't really drop.  There's nothing worse for a Frog than giving up and being mistaken for someone willing to fight.
