[ARCHIVED THREAD] - Help! What's the difference between these two low profile gas blocks?

Will someone please distinguish between the 2nd and 3rd gas blocks on the page and explain why one is better than the other.

I'm thinking about putting a 10 inch Troy rail on a carbine length gas system. Will either do the job?

Thanks!

I just put the third gas block under a Larue forearm today, I've used the second one in the past. The second will not fit under a forearm like the Larue or DD. The third gas block will fit under the forearm, but it will not cover the holes drilled in a barrel for a standard front sight base.The 21.00 gas block is better as long as your not covering holes for the taper pins.

Are you saying that the DD clamp-on gas block will fit under the LaRue handguard? I have a LaRue coming and wanted to use the DD gas block but was under the impression that it wouldn't fit under the LaRue. Talking .750" barrel here. Thanks.

I had to read the above post several times to figure out where you saw anything in this thread about the DD clamp on gas block. I can only assume you misread the line where he said that the large YHM gas block will not fit under a Larue or DD railed handguard.

This is what I'm saying, the large YHM gas block will not fit under either forearm.

Yep, I mis-read it. I try to screw one thing up each and every day. On 5/30/08 this was it. Thanks for pointing that out.

+1 on the YHM-9383. I've used 2 on my last two builds, they work great under a ff tube.
