Guess I should have asked before I ordered.
I grabbed their Pin Upper Vise block.

Needing to pull a flash suppressor and hope to build my 10mm upper some day after acquiring the rest of the parts and figured I would give this piece a try.

While reaction rod is the way to go my understanding is they don’t work with PCC builds.
This seemed like a better option than the cheaper plastic clamshell vice blocks I have seen.

Hoping I am not wrong but at under $20 I am not out much unless I damage an upper.

As far as their stuff goes, quality made and works. As for the flash hider, I would clamp the barrel in place to remove. See if you have an old belt your not using to keep from scratching up the barrel.

I don't have the pinned vice block...but I have this upper vice block from them...it works well and has never marred an upper (5 builds)...

I also have their lower magazine vice block...

IMHO Plastixrevolution makes a very good product, especially for the money...I don't think you will be disappointed at all.

Arrived.
Very well made piece. Seems to work alright so far.

It looks well made. I usually just clamp the barrel in thick leather strips and twist off the hider.
