Recommendations for gas block

[Crowesnest]

I am thinking about replacing my current A2 fixed sight with a dedicated gas block. Any recommendations on which one? From what I've read, all gas blocks serve the same purpose, but are some better than other or am I really not gaining much at all by replacing the A2?

Depends. What purpose does it need to serve, if other than just being the gas block? Does it need to fit under your handguard/forearm? Do you want a rail on it? 4 rails? Budget?

Railed, preferably four, as I am thinking about replacing the A2 with a flip-up sight. I think i'll be fine with a fixed gas block. As far as my budget? less that $100 is good.

Those will work plenty

Pinned gas blocks are best because they are strudier, set screws are second and then the clamp ons.

If you aren't attaching a bayonet or a vfg (that would be funny) on the gas block you should be ok though.

No bayonet... any particular names that you might care to throw out there?

Sorry, I didn't look into railed gas blocks when I was looking for mine. I just went with a low profile gas block that is covered by my FF rail. I attached my front BUIS to the FF rail.

I went with a YHM lo pro gas block. It seems that the brand name isn't a big deal, much like lower receivers. Vltor, YHM, LaRue, they all do the job.

However, since you want a railed gas block and will be hanging stuff off of it, I would try to look for one that is attached with set screws. You may also want to have your barrel dimpled. I would ask Randell from ar15barrels.com as he is the resident AR/firearms expert.

Okay, so I found my gas blocks... question is, what size? I have a CMMG upper that I bought from Mark's Armory. Unfortunately, the spec sheet does not indicate diameter of the barrel, so should I get a 1.10, .750, or .936 diameter block?

[RRichie09]

just measure the diameter of your barrel where the gas block would sit.

It can be done with a regular tape measurer.
