I purchased the .936 set screw model for a heavy barrel 16" carbine .458 SOCOM build. I found the Sadlak Gas block to be well made and well finished. It is parkerized. The adjusting screw is on the right side. Lock screw is on front. Nowhere in my searches did I find dimensions for this gas block. I measured this gas block up so as to help others on their build and to perhaps aid in handrail fitment. No Allen wrenches provided. Gas block and set screws only. I also removed the gas adjusting screw and lock screw and put on some never seize compound. I set the gas block by starting with the gas screw backing out 1 1/2 turns from the seated position. Place 1 cartridge in mag and chamber the cartridge. Fire rifle in a safe direction. Action should eject empty casing and lock the action open. If the action doesn't lock open, open up the gas screw 1/4, turn and repeat the process until action locks open. I give my rifle 1/4 more turn open after it locks the action open. Lock adjusting screw with the set screw on the front of the gas block. Don't over-tighten. Your firearm should be ejecting at 3 o clock to 4:30 o clock position. If the gun is discharging forward of 3 o clock it is over-gassed, and you should close the gas screw some. If the rifle is ejecting from 4:30 to 6 o clock position you are gassed and you need to open the gas screw a bit.You don't normally need to change to a heavier buffer with an adjustable gas block. A muzzle brake and adjustable gas block can cut your recoil and help your firearm stay on target better for faster follow up shots.These are the measurements on the .936 gas block. Other sizes may vary. Allen wrench size for set screws to lock gas block on the barrel is 3/32" Allen wrench needed for adjusting screw and set screw is 1/16"
