gas block
Does the job just rite

Works like it should
Bought the steel version after hearing some people not liking aluminum blocks too much. Mated this to a NEA 14.5" mid length. Dimpled the barrel a bit and this sits in there rock solid. No complaints.

Solid piece, great value
Installed this on a NEA 12.5 barrel. Went in without a hiccup. Make sure you re-check your set screws after you fire your first rounds. Mine had came loose and I was getting FTFs. Re-tightened and worked flawlessly afterwards. This gas block will go on all my future builds.

Really good block
This block i put on my lothar walther 10.5" barrel with my low profile floating rail. Fit is good, built strong. I'd say just as strong and as good as another block of the same exact design but at half the cost. Won't disappoint.

Exactly as expected
Worked perfect, and functions 100%- Nothing more to ask for!

Good value
Does what a gas block is supposed to do, finish is reasonable, wonderfully priced

Will be back for more.
As much as I want to use super cool, high end, pricey gas blocks. They look the same, do the same job, and these are substantially less money Really hard to use anything else. Planning to use one of these on my next build too.

Absolutely solid
Not installed on my build yet, but from handling it it's absolutely solid. An amazing value for such a well built piece!

great value, great product
great product for the money. comes with everything you need...not much more to say about it other than it works and looks good under my free float hand guard. installation was bang on, slid over barrel with no issues.

Great Steel Gas Block
I went with this block over the other Micro-Profile aluminum one offered on the TNA website. I have no doubt the aluminum block is perfectly fine but I like the idea of a solid steel piece. The block fit snugly over my barrel but not so much that it would scratch it, and after I had it installed there was plenty of space between it and my NEA free float handguard. I got the block on sale for $33.27, just a little bit more than the aluminum option, at that price it was a real steel... get it?

Never going to break.
Solid steel block, low profile, fits right under free-floating handguards. ||This thing is never going to crack from use.||TIP FOR FIRST TIME BUILDERS|Draw a pencil or soapstone line from the gas-port out towards and onto the front face of the block, draw another one on the barrel coming out from your barrels gas-port. Line these two marks up when you install the gas-block and you won't have any issues with pressure or gas-flow.
