Dissipator

Your barrel has to be cut with the proper reliefs for a fixed fsb. Not all are.

 

no. you just need to contact the barrel maker/supplier to see if your barrel has been profiled to mount a fixed fsb if you plann on using one.

 

For a true dissipator dont you have to move the gas hole on the barrel as well?

 

You could get a clamp on front sight, like a folding one from PRI or YHM.

 

That kinda depends....
You could build a dissapator with either a carbine or a mid-length gas system, which remains intact (in the same place) while a front sight base is affixed in front of it. The forward FSB isn't connected to the gas system, of course.

 

Yes a true dissy will have a rifle gas system. A mock dissy will have to have 2 gas blocks if you want a fixed FSB up front.

 

Easier than a thousand words, right?

IMO a dissy is not just cosmetic. to have the "dissipation" the gas system should be rifle lenght.
not just be a dissy-look for the range buddies

 

real dissys can be problematic, not enough dwell time. mock dissys have that problem sovled. IMHO its gotta work gud, then look gud.

 

Read the fine print. Those are "mock" dissipators. Not that there's anything wrong with that.

 

Honestly a mocks will be a better choice. We are anxiously awaiting our gratuitous pron.

 

I really liked mine before the boating accident. I had a carbine length gas system.
