.936 Gas Block help

[brodezoe]

Hey all,

I have a BHW bull barrel coming my way in a while and am putting it under a Daniel Defense Lite Rail. I'm trying to find myself a .936 low profile, clamp on gas block. I don't even know if it's possible, but I'd rather find a clamp on instead of set screws. There's very little space inside that rail system and I'm just wondering if any of you have seen anything that would meet my needs.

In relation to that, are my worries about clamp on vs. set screws unfounded? It just seems like the least invasive/destructive way to attach the gas block.


Thanks for the help!

This is the only one I found www.midwayusa.com/product/734312/sadlak-clamp-on-ar-15-lr-308-936-inside-diameter-aluminum-matte . Good luck in your search.

That is also the same gas block at Brownells.

I did find this and it looks like the most low profile gas block in .936"

When the gas block is installed correctly and you dimple the barrel for the set screws, it is very effective. I also prefer clamp style gas blocks, but have not had one issue with my set screw types.

I've never had issues with the set screw type. I suspect that the clamp on version is not a real common animal in a low profile configuration.

It might be a bit of work with a grinder to make your own up unfortunately. You could take the JP ADJUSTABLE block from Brownells and grind the top rail ff and slip it in your hand guards. Mine would clear a regular Hogue FF Tube but I have no idea of the dimensions on yours.

I have a few big barreled AR's running the set screw type block. If they degrade the accuracy I am chapped because they shoot so well now I can't imagine what they would be like with the other system!!

Thank you guys. I think I'm just hesitant to do anything to my still unborn beauty of a barrel. :-) I've been thinking of the Troy Industries block that letaz posted and I'm thinking I'll go with it. Just wasn't sure what the combined wisdom of the forums might add and wanted to see.

Thanks again for all the ideas and thoughts!

I prefer the clamp on gas blocks. I have 1 DPMS rifle with a set screw gas block and it has a lot of gas leakage around the block. I have built several rifles with clamp on gas blocks and have not had any gas leakage problems with them. Perhaps DPMS didn't install the gas block properly on my rifle. I don't know. This is just my experience with set screw gas blocks and may not be typical.
