I'm working on a parts list for a build for my wife and she wants a Flip-Up style Front Sight Tower.  She was interested in both the VLTOR unit and the YHM.  Looks like the VLTOR offers both a clamp style and pinned.

I need to send her barrel to ADCO to have a muzzle device pinned on anyway so would you recommend going for the pinned front sight tower as well?  Or, would you recommend the clamp-on style to save the $90ish ADCO would charge to pin on the sight tower?

If you suggest the clamp-on models, how difficult is it to get that thing perfectly straight?

Get her a low profile gb and free float rail with flip up sights...

That would be may suggestion also.

That's what I mean.  She wants a flip up front sight tower, not a flip up on the handguard.  She doesn't like the way longer rails over a LP gas block look.

Clamp on has the best chance of being accurate, pinned on is the most reliable. Is it a combat gun or a target gun?

Take her back.

I kinda agree with this. If it is just a range/fun/comp gun I'd go clamp on and not worry a bit. I like pinned for duty guns though.

FWIW, ...

I made a dissy style with the Armalite clamp on FSB.    I was initially worried about it being unreliable vs a pinned.  If I had only stayed off the internet I never would have known the difference.

YES, a pin will be mo stronga.   But I sure can't tell.   The gun is a farm gun.   It gets knocked around slightly and has never moved on me.  Im sure a soldier can break it in short order.   But be realistic.    

THE BEST advantage for clamp on fsb is that you can zero with the front sight and then have a rifle with mechanical zero at the rear too.  

A ways back someone, (MillMonkey?) got a vise and a BFwrench and then twisted a vltor clamp on to the point it was destroying the index pin, receiver and sight tower.   The clamp on the barrel didn't budge.

found it..   scroll down a lil

I have several of the YHM clamp on type in use.
The advantage of the YHM is it can be removed and replaced with a pinned FS.
