Archived [ARCHIVED THREAD] - Adjustable Gas Block vs Adjustable Gas Tube
Posted: 5/1/2009 8:21:54 PM EDT
I'm building my M4.  Got a Larue 9' forearm on a M4 16 inch profile barrel.  I'd like to be able to use an adjustable gas block (PRI), but I'm concerned that it won't fit under the forearm.  So, maybe it would be better to use a low profile gas block and an adjustable tube (Armforte?)?  Anyone have experience with either of them?  Any thoughts on the reliability of either?

The heaviest bullet I will shoot is the Sierra 77 MK.  Do I even need to worry about the gas system or just put on a regular carbine gas tube?

Thanks!
