Has anyone tried a dissipator - a rifle length gas system on a 16 inch barrel ?

What's the verdict ?

A guy that I shoot with occasionally has one.  Looks interesting, but I haven't shot it nor have I asked him how it runs. 

I know there are a bunch of people who have mock dissys with a low profile gas block on either carbine or mid-length gas barrels and put the FSP out there.

I believe most dissipator set ups coming out from manufacturers today like bushmaster, palmetto, spikes, delton etc, are actually mid length gas with a low profile gas block and a pinned on fright sight post.  THe front sight post doesn't actually act as the gas block like they normally do, it's mostly to extend the sight picture out farther and be able to use a drop in non free float 12" rail. 

Personally i think they look bad ass and really want one.  I was about to pick one up from delton, however theirs doesn't come chrome lined, which is a no-no is my book.

Thanks for the responses.

Yeah, the Del-Ton is the one I'm looking at.
Del-Ton says it has a full-rifle length gas system with the gas port opened up.
Looks BA and supposedly it reduces the recoil down to next to nothing. Thinking about one to introduce the kids to the AR platform.

really?  I never saw it say rifle length gas before so i assumed it was like the rest being made these days. 

Good luck with it.

Just be aware that no two rifles run exactly alike.  Having said that the true "rifle length" gas Dissy like the Del ton might be extremely finicky and is often the case on a rifle to rifle set up.  With the greatly reduced dwell time and the gas port size that Del Ton uses many will only like to run on a true rifle buffer and spring so that often means a simple upper swap is not a reliable option.  Your kids are probably better off learning on a .22 set up.

 We just sold a bushy. It was a mid length. It had 2 gas blocks.  Forward gas block is used just for the front sight.  Rifle length dissys are finicky with ammo.  Mid length is a good comprimise.

I got an AR that recoils like a .22 rifle.. It weighs as much as 3 AR's in one

Is that your service rifle for EIC matches?
Mine is at 18 lbs. fully leaded - front and back
When I shoot my Compass Lake Engineering .22 upper it barely recoils

Damn...I think I have 3/4 in the back and 3/4 in the front.  Everyone who's ever played with an AR before always get surprised by the weight.  I always gotta have my hands ready so they don't drop her... 

Dang you guys give me a lot to think about. I appreciate it. 

Thought about .22 for training the kids but they are 10/22,  bolt .22 and bolt .17 hmr proficient so can't really justify the expense for another .22.

Side track: if you haven't tried .17 hmr you should. It's a blast and SUPER accurate. Like minute of  ragged hole at 50 yards.

I'm thinking I'm gona pull the trigger on this one ( the Del-Ton ) just for kicks.   I"ll probably try a dedicated lower with a Wolff reduced power buffer spring to aid in cycling. I don't really shoot any steel case ammo, mostly xm193 5.56, so hopefully cycling will be OK.  ( If not it's going to be a really expensive paper weight and conversation piece. )

Note:  Buy your 5.56 from OGC, they have awesome pricing and service. ( I'm not associated with them but how's that for a shameless plug )

It's a heavy contour barrel so recoil impulse should be even more minimal.  We mostly shoot from the bench anyway so extra weight shouldn't be a factor.  Hoping it won't be 18 pounds though.   

I'll provide a range report once I test it out. And if any one sees me at the range ( Lanky Haole guy with goatee and dissipator ) come on up and I'll let you try it out.

Nice!   

Looking forward to hearing how it goes for you.

I also get most of my bulk ammo from OGC.  Great pricing and they try to keep a steady stock.

I only shoot my 15 lb AR in the standing..

Dang, you guys can shoot mine and I'll get my work out doing curls with yours ( muzzle down range of course )

If you like, I can see what I can do to arrange a time for you to shoot it (just have to figure out how to bring it to the range on a moped )...It's actually quite pleasant to shoot.

Range report:

Delton Dissipator upper. Rifle length gas system. Put A1 triangle handguard on it and looks badass.

Mounted it on a CMMG lower and it ran like a dream with XM193 5.56 ammo. didn't get a chance to run it with anything else.

Fairly accurate, not one hiccup and kids loved it    ( Maybe 100 rounds through it )

By the way, there's a mock dissy upper (mid-length gas) available on PSA website ( sans BCG and charging handle ) for 429.99.  Usually around $15 shipping.

I would love to buy this but just recently ordered a mid-length upper from them.

Some with rifle length gas systems are finicky when rapid or bump fired. the dwell timing is a little off due to the gas system almost at the end of the barrel.

I building 2 custom dissapators in 762x39 right now.  Using carbine gas system.

I have a 16" Noveske SS barrel with an intermediate length gas system. It's between the mid length and rifle length gas system. It's meant to duplicate the soft feeling of an 18" barrel with a rifle length gas system but in a compact 16" package. My set up includes a PRI/MSTN quiet comp and an adjustable gas block. I like it as it makes my AR-15 (223) feel like a loud 22 LR; the double taps are also very fast.

I would reconsider the 16" barrel with rifle length gas as it can be too unreliable.

Sweet !  Let me know how they turn out. That would something I would be interested in.
