Ar-15 Gas Block Question

[264Magnum]

Since the Magpul hand guard comes around the gas block, a railed gas block might not even fit.

Didn't notice that. I might have to go with a two rail instead of quad. One railon top and one on bottom. have to look at that.

Why on earth would you want a railed gas block?

If you're wanting to keep the factory plastic hand guards, get a gas block with an integral flip up front sight like a PRI.

Yup..

Lo pro gas block, Troy TRX Xtreme battle, flip up sights (Troy) = Win

Try a YHM flip FSB if you're going to keep with a carbine length HG.

Still thinking of a rail gas block. Ok your opinion of the best flip down front and rear sites?

Troy are generally considered to be "best", but you'll pay for them.

You can get a set of Magpul MBUS for less than one Troy sight, and they accomplish the same goal.

I guess I should be more specific. I want to remove the factory gas block and put a quad rail gas block on it.

Why? I have a RRA AR with the railed front gas block. It has been a PITA to get a gas block height front sight. At 1st I put a hand guard height front sight on my quad rail handguard... I didn't like it at all, slower sight picture acquisition. Why sacrifice an inch of distance between your front and rear sight?...That will just make you less accurate.

I picked up a "flip" front sight to go on the gas block yesterday, and sighted her in and ran 200 rounds through her today... I don't see any real advantage to having the railed gas block with a flip front sight. It is much heavier than a standard front sight/gas block.

What does that mean?
