| Wanting to replace my A2 front sight with a low profile gas block. What is the best way to go. I herd that the ones with the set screws will loosen up over time and move covering the gas port holes. What are you guy's using? |

While set screw gas blocks are technically weaker than ones with pins... i haven't actually heard of one loosing up if it has been installed correctly and red locktited. But then again i haven't been researching that either.
I used a YHM low profile with set screws... worked great.. no complaints. I personally think people get a bit too fancy with gas blocks... i mean in reality it is just a piece of metal with a hole drilled in it. As long as the hole is in spec and it isn't made in china you should be GTG.... no need to spend $60+ on a low profile. Another option... the cheapest and strongest would be just to cut down your existing sight into a low profile. Easy to do and the strongest you will find anywhere. Costs nothing as well. |

Be advised that if you cut your FSB into a low profile gas block, and you decide to go back the the OEM configuration you will have to buy a new FSB and send it off with the barrel to be pinned on properly, and will cost you ALOT more in the long run.. Don't ask me how I know...
ETA I have a VLTOR set screw gas block on one of my rifles, and it has had no problems coming loose. I did buy the dimpler tool to install it properly though.. |
