So I bought a PSA "dissipator" upper a while back and had the muzzle device pinned/bayo lug removed:

What options do I have for "drop-in" rifle-length handguards that don't require me to pull the barrel out of the upper in order to fit a custom barrel nut and will work with an A2 sight?

I know about the magpul MOE; any others out there?

Edit: Ideally either has a bottom picatinny rail or can mount a picatinny rail section - I have a picatinny-mounting forward grip I want to use with it.

Yep, Magpul MLOK

The upper is mid-length, are you looking to put a rifle length hand guard on that middi upper?

Well for full rail, there's the Midwest industries drop in and also the Troy MRF.  Can't remember which one needed the triangle cap to be snipped off, but they're both solid.  Just on the heavy side

Oh, my mistake, thought it was rifle length.  No, just want a mid-length then.

If you swap out that sight tower with a low-pro gas block, your options open up.  You  pull the tower, ditch everything but the barrel nut and gas tube, attach the hand guard mounting hardware, attach hand guard, and viola, free floated for just another $50 and 15 minutes.  If you are just looking to jazz it up a little, the magpul mlok hg is very good, plenty of mounting options.

Read the barrel description. It's a mid length gas system with rifle length handguard.

Yeah, that's what I thought the first time, thanks:

Barrel is finished off with a pinned F-marked front sight post in the Rifle position with sling swivel,  rifle length handguards, and an A2 flash hider.

Thanks, but  more work than I want to do at this point.  Want to keep the FSB.  I'll keep looking at my options for RIFLE LENGTH drop-in handguards.

A dissy is a rifle length gas system with a 16" barrel.

You could put m lok rails on the stock hand guard

Okay, after seeing this, I have a better understanding of what the deal is.

 

PSA incorrectly states that the gas system is mid length.  A rig designated as a "dissipator" has a rifle length gas system.  You definitely need a HG compatible with rifle length if you are going with drop-in.

A dissipator is  a carbine or mid-length (preferred) gas system with the distance between the barrel nut and the FSB being rifle length. There is a low pro gas block under the handguards.

There is another version similar  to this called a Kino, which is a carbine gas system with the distance between the barrel nut and the FSB is mid-length on A 14.5” (or shorter - like 12.5”) barrel.

That would never work due to dwell time issues.

Bushmaster’s original Dissipator was a rifle-length gas tube to the FSB and the barrel chopped to 16”. Short barrel, full-length sight radius. “Best of both world’s?”  It should work fine depending on the size of the gas port hole drilled in the barrel. 

If you are seeking a railed handguard, The KAS M5 RAS is a nice option. Little heavy though. Totally drop in.

No.

Bushmaster came out with the first civilian AR-15’s actually called the Dissipator which had shaved-down gas blocks at the normal carbine length and then a “dummy” A2 sight block up in front at the rifle position.

Didn’t Del-Ton make one work with rifle length gas? 

I would personally  just build another upper.. 

What was the point of  buying a dissipator, just to turn it into your regular run of the mill upper?

These things were always a novelty, run with carry handles and stocks... maybe a MOE hand guard wouldn't kill the novelty as much?

Always loved the look of a "commando" m4, and these were just slightly longer versions, like the Kino and then the dissipator... 

With these "other firearms" now... I have a Kino on my short list...with a brace ofcourse.

 

And thanks to @High Exposure

cause i never knew it was called a kino....

Because I had a lower sitting around and got this upper for very cheap.  I have no desire to make an "accurate recreation" of a historical dissipator.

This is a great option.
