Wanted to try one for use on a suppressor host. Easy on/off for when the suppressor was off.
I think the threading might be off on this one. SUPER-tight threading on Faxon 10.5 pencil. Thought I was cross-threading and kept backing it off.
Tried it on two Ballistic advantage barrels, would not thread on to those at all.
Tried a Faxon 16" pencil and it threaded on that a bit easier than the first.
not sure if Faxon made them this way, might just be this unit. ___
Performance: On 10.5 pencil was okay as a flash-hider. Weight is okay (bit more than birdcage). Has a tuning-fork 'ding' when you shoot. Noticeable by the shooter & those within 20'. Others who shot it said it was annoying. That's just part of thin tri-prongs.
I'd probably rate this 4-5 stars if it didn't have the fitment issues. But it does.
