Dissy Comparo Updated

Ten years ago, Willard made himself a Dissipator too!


 

His upper came from Spike's Tactical.  My lower did!

I noticed they do things a little different from Palmetto State Armory.


They used a little stub of a gas-tube to keep the handguard cap from spinning.  The lighter barrel profile forward of the gas block also shaves about two ounces.


 

PSA uses an allen head screw.

What that means is USGI triangle handguards won't quite fit in the handguard cap.  A little bit of carving should allow them to work, though.

The quality of the handguards that come from PSA is disappointing.

Happily, I had a set that came with the upper I used making my M16A4 clone.  Much better fit.  Bonus!  They're 2.2 oz. lighter as well!

Something I've noticed about dissies in general and mid-length dissipators in particular is that they come and go as a stocking item.

There's long gaps where nobody makes one then someone will get brave and put a run up for sale and it takes forever to sell them.

Willard, as I recall, got his on sale from AIM Surplus.  Mine was deeply discounted in the Easter sale.  They're out of stock now.

  1. I was looking at doing a dissipator pretty closely when I put together my first AR but decided in the end to just do a 20" instead. I imagine a lot of folks did the same. The extra 4" isn't that big a deal and parts are easier to come by. I've got to admit though the dissy still catches my eye every once in awhile.

    1. The Dissy is not my first AR... That was Kaylee and there's a history of her here. I think I made every misstep you could with her until I settled on making a 14.5" (NFA registered) M4 clone.
