Gas Blocks

[CoryCop25]

What are the advantages of a high end low profile gas block as opposed to a cheaper version? Yankee Hill low profile gas blocks are about $25, Midwest Industries are about $35, Larue and Daniel Defense are about $65. I can see weight being a factor but if they all fit for the specific application, what would be the deciding factor to spend twice the money?

I simply cut my front sight. Besides that, cant help much. Is it visible?

I have used YHM and Midwest blocks on builds for people. They attach with a set screw and I drill a small dimple in the barrel for them to sit in along with locktite. The ones I have used fit very well. I'm not sure how durable one is compared to the other but I can't quite justify the price difference without some solid evidence as to why I need to go with a much more expensive brand.

If you bought at Colt...

Using your factory Colt FSB and machining it to a low profile configuration is the best option. Maintaining the pinned factory gas system ensures reliability that you won't get from an aftermarket gas block.

Depends on what you intended purpose will be and what you want to spend but I have used Midwest low profile gas blocks on builds with no issues. Is this just a target/hunting/plinking rifle? Or do you intend on torturing it? A gas block is a gas block unless you want an adjustable one or one that will endure some serious abuse. Just look at the standard FSB, not that complicated construction steel is steel designed to work.

This is going an a brand new DD CHF 16" Middy under a 12" DD lite rail. I will be using this for classes that may take me out of state so I don"t have to go through the mess of transporting my SBR. If I was converting an existing set up with a FSB I would shave it but this is not the case.

Hey, I noticed on adco's website that they offer a machining service to properly attach a lo pro gas block with the 4 set screws in the side... not sure if that would help any but....

I also know of people using the inexpensive lo-pro blocks with the single set screw at 6 o'clock and drilling a small dimple in the barrel to lock it on a little better.

Not too sure besides that. Good Luck Brother! Be sure to post pics when she is done!

Thanks for the hook up. I want to do this 100% myself. I do currently dimple the barrel and use red locktite. I'm just concerned with price vs. durability and weight is second.

Try Rockset instead of red loctite. The gas block can get very hot and loosen up the loctite. Rocksett is good to a much higher temp. Also, stake the gas block into and over the set screw.
