Does anyone know if one of the adjustable kies gas blocks will fit under a troy vtac?

According to their specs it says it requires a 1.75 inch tube and the vtac is a 1.5 I believe. I was just seeing if anybody had tried it.
I'm not running it myself, so these are just my thoughts, but, the 1.75" is for totally round tubes, like the YHM. The Troy/Samson/MI have the upper channel specifically for lo-pro gas blocks, which brings the 1.5" ID out to 1.75" under the rail, so it should work fine.
I'm with you, why introduce complexity where none is called for?Originally Posted by Livnoutdoorsxd9
I chopped a 16" 6.8 wown to 12.3", had to get at the gas port with a drill bit.
Recently bought a 300 BLK, 9.5" barrel, didn't cycle, had to get at the gas port with a drill bit.
Unless you have some compelling reason to NEED an adjustable GB, I am at a loss as to why in the world anyone would buy one at all.
I have a brand new JP adjustable GB, never used and hope to keep it that way.

I have the kies gb under a vtac alpha. Fits just fine.

I like the Syrac adj block. It has detents that lock the adj screw so no loctite or worry of it adjusting itself. Fits under even the new ultra slim HG's.

If it's a common setup of caliber and gas length, I'd just get a std one though unless you plan to shoot suppressed a good bit.

I agree with you the best thing is to simply stay away from those situations that require more unwanted complexities like many carbine ported barrels that should not have been made the mainstream market in the first place.
Once the situation is there the adjustable gas block is the next sensible option to avoid the unwanted stresses put in the other parts. Some people do not even know they have them until the find the hard way. Then they learn.
I was considering getting one because the kies is about the same price as most regular low pros. It just seems like this would be easier than experimenting with different springs and buffers to get my gun cycling correctly, if doesn't straight out of the box. If they are more trouble than they are worth the I will stick with the yhm low profile. Thanks in advance for any advice.
Ask the mfg of the barrel what what spring/buffer they recommend. Most of them make uppers too so they will know what works properly. If they sized the port correctly, it should be a std carbine buffer & spring or a std rifle buffer & spring, depending on stock you go with. This is usually not a problem from a good barrel manufacturer / seller.
