| I have a flat top upper with a standard front sight, which of course is in the way of a scope's line of sight. I don't like sawing parts apart; not much resale value there, so with all the gas blocks advertised, which is best? I'd like to have a sling swivel. |

My wife and I just went through this same thing..below is the thread that I started. Not to long ago we replaced her handguard with some drop in YHM's. So just this weekend I bought a YHM single rail gas block and a handguard cap, so that i can replace the fsb. www.ar15.com/forums/topic.html?b=3&f=4&t=363645 |

Check out PRi: Precision Reflex folding front sight/gas black. Pricey but excellent. Just push out three pins on your exsisting FSB, and replace it with one of these. |
