Gunsmithing Need Vltor VST-2P gas block info/help

[rmc51]

I have an A2 pinned front sight base that I would like to replace with a Vltor VST-2P gas block (I think, It’s what I’ve been looking for). Is there anybody that has installed one of these? and could answer some questions.

I’m trying to get rid of the front sight in the scope. It has a TA31a and the A2 FSB sticks up into the view of the scope. I do not what to put on a clamp or set screw gas block with fold up sight. I believe I found a direct fit replacement for the stock pinned A2 front sight, but it is not cheap($225), and I’m want to make sure this will work/fit.

Vltor Weapons Systems - Vltor Sight Tower (VST)

Is the VST-2P a direct fit replacement for the A2 FSB. Can I unpin the A2 from the barrel and install and re-pin the vst-2p and it will be clocked correctly on the gas port?

I called and spoke to Vltor, tried to speak to a Tech Support person, but could not get past the CSR girl, and I don’t think she knew what I was talking about. I don’t think she understands direct fix replacement. She was not very sure of herself. I was left unsure of her info.

Anyone here know anything about these?

Short answer: No, it is not.

Again, no it will not simply replace the FSP like you describe. I am pretty darn sure that it would be impossible to pin any other gas block or FSP onto your barrel other than the FSP that you now have. The issue you are facing is that your current FSP is already taper pinned specifically to your barrel. Trying to get another gas block taper pinned on and lined up with the barrel's tapered holes is going to be darn near impossible.

My suggestion would be to shave down your FSP into a low-pro gas block and get a rail system that is long enough to cover it.

^^^ this would be the correct answer.
The FSB is match drilled/reamed to a particular barrel and are not interchangeable.
Bob the factory FSB.

Get the Vltor FSB clamp version, taper pins have nothing to do with it. Knock the pins out of your factory FSB, slide it off and slip the Vltor on, align it properly and tighten the 2 cross bolts...done.

You're stuck with the clamp on version if you use your current barrel. Believe me, the time, trouble and difficulty involved in lining up the pins wouldn't be worth it.
Buy the clamp on and rock on!
