Question 1, can you use the YHM FF wrench for removing regular barrels.

Question 2, can you use the govt. issue wrench Found Here for ust with YHM FF barel nuts.

Question 3, Has anyone modified a YHM midlength lightweight forearm to be used with a regular carbine FSB?   Can it be done?

NEW QUESTION: where to get the best action block.  I think I want one like Bushmaster sells Here but is there anywhere else to get it?  Thanks

1: Yes
2: Yes, if it hasn't been bent out of tolerance.
3: Not that I know of. You would need someone with a machine to remove the barrel, and then the tube would have to be timed each time you installed it.

The YHM wrench is easier to use on regular delta ring assemblies than the DPMS wrench that I have...you don't have to put very much pressure on it to get it to slide into the teeth on the barrel nut.

I recommend the while Delrin DPMS style of action block, personally.  I had the clamshell, but ditched it after I got the DPMS.

If you plan on using anything other than an A2 or flat top upper (like an RRA EOP upper, or a DPMS Lo Pro), the clamshell won't work.  

I'm not sure about question 3...what are you trying to do?  

Where to get a YHM barrel wrench for reg. FF// DD, LaRue?

Quoted: Where to get a YHM barrel wrench for reg. FF// DD, LaRue?

As far as I know, the only place to get the YHM wrench is direct from them.  If the DD and LaRue tubes use a standard 3 piece unit...tube, barrel nut, and jam nut, then the YHM will work.  I haven't used the DD or LaRue tubes, so I don't know how they work.  

The YHM wrench works great on YHM tubes
