Have a question concerning a certain type of low profile gasblock. Are the ones with the two setscrews in the bottom worth a crap? I am going to use one and give it try as it is already laying around here but kinda nice to know what to expect. I thought about possibly putting a couple dimples in the bottom of the barrel for the screw to set in if that seems like a good idea. Even if I do not do that I am going to blue loctite the setscrew for sure. Anyway if you have experience using this type let me know how it has held up...Thanks

I had a midwest industries .750 lo-pro gas block that went on so incredibly tight that I don't think it even needed a set screw.

A dimple in the barrel is a good idea.  I have since gone to a clamp on solely because I wanted adjustable gas.

I use the Kies low profile adjustable blocks, but do have to drill a couple of indentations in the barrel and use RED Locktite (high temp) to install.  They run about $33, and are machined from high quality steel.  Joe Bobs keeps them in stock for me.

Thanks I was thinking just a couple little dimples with a drill bit might be a good idea.. I can see some people attempting this and ending up with a couple extra gas holes

There are gas block dimple jigs available.

That is definitley a fancy way to do it but I would just be doing it the simple way. I would tighten down one setscrew. Center punch the empty hole. Move the setscrew to the other hole and center punch the other empty hole,remove the gasblock and clamp the barrel in my padded drill press vise and drill each dimple  punchmark I made.It would not exactly be rocket science.That jig might be alright if you were in the buisness of doing such things all day but for me it would not be worth the expense to do a simple procedure, that is for sure..Thanks

Oh Jesus.  Please don't tell Direct-Drive that you possess even an inkling of human ingenuity.  If you aren't using every new fangled tool out there, to "do it right," you are nothing but a monkey wrenching caveman, doing things on the fly and that just isn't right.

Doing it that way you give up easy the easy alignment that the jig provides. (the reason for the jig)
Just measure for front to back and match-mark for left to right.

LOL You should see my freefloat handguard homemade nut installation tool. Just took a piece of 1/4 inch thick flat iron and drilled a 1 1/4 inch hole through the center on one end. Then I drilled three holes that correspond with the freefloat nut pattern and spot welded three little pins in the holes. Then welded a cheap socket on the end to put the torque wrench on. Cost me nothing to make it. Just was scrap laying around and I enjoy doing this kind of stuff anyway..These Cos would go broke if they had to depend on me to buy their stuff I will not even go into my 2X4 wood upper reciever vise block I made with my router and table saw and hand chisels

Trust me.  I am right there with you.  When I was in the Marine Corps, you wouldn't believe some of the stuff we had to do in order to keep our helicopters flying.  Most of the time, we had stuff taken off, cleaned up, new major part in, and the plane just about buttoned back up for flight, before the "supply" system finished delivering all of our parts.  If we waited on supply, we would have operated at Air Force pace.

I have always made stuff since I was a little kid. Grew up very poor,well am still kinda I had to improvise and fix stuff or I would have had nothing in life when I was a youngster. Well not to get off the subject but my info on making stuff is just to show you if you are not lazy and are not just looking for the easy way to do something and actually want to have the satisfaction of using your own tools you made rather than just  buy the stuff you need, there are satisfying options to just throwing away your money. Like I say enjoy making and doing  this stuff myself. It just has a satisfying feel to it. Not to mention the money I save...Its probably not for everyone to make this stuff but its a option I am very happy to have.   Thanks for serving. My Dad was in the  Marines back in Korea...

Damn dude, I'm new here but I know quite a few Marines who wouldnt complain about the pace of F-15E's or A-10's overhead. And I know a few who wouldnt complain about the pace of the C-17 that took them home, or unfortunately to Landstuhl.  

Sorry, off topic, I use the gas block I'm installing as a jig to drill dimples

OT for sure, but I will say one thing and I am out.  Fixed wing planes are nowhere near as labor intensive as helicopters.  When it came to repairing helicopters, we would do jobs in 2 or 3 hours with two or three mechanics, that it would take an Air Force crew 8 hours with an 8 man crew.  They operate like a union.  1 guy pulls cannon plugs, another guys unrigs the engine controls, another guy pulls the engine cowlings, another removes the exhaust, a different one removes the driveshaft, one hooks up the crane rigging, another operates the crane, yet another removes the bolts holding the engine to the airframe, another one mounts the engine to the ground support equipment, while another one drives the engine to wherever it is going.  An exaggeration?  Maybe ever so slightly.  But you get the picture.

He doesn't know what that stuff is.
They had hot air balloons when he was in.
