if mounted on gas piston AR15 near the gas block will it overheat? If so then how far away does it need to be during sustained use?

The Gas Block is designed to prevent gases from escaping, and also to cycle the bolt toward the rear of the Upper Receiver. This inertia removes the spent case via the extractor arm and a newly unfired round is chambered when the Bolt Carrier Group retreats back into Forward Battery. You don't have to worry about the placement of your Optic because it sits on the rail, no matter where you choose to install it, Gas Piston or Gas Impingement. All the gases that do escape, will most likely be trapped and dispersed by the hand guard, Quad Rail, etc... Any Gases that do manage to escape out from the vent holes in a hand guard won't cause any heating issues even in sustained use.

I wouldn't mount this to the gas block. The screws are probably too wide apart. This rail is typically used to tilt the scope down to increase the elevation adjustment. I don't know of any rails specifically designed to extend from a gas block.

I locked mine down tight to zero it in with about 50 shots from that platform. I took about a hundred shots to tune into zero repeatedly and it worked well. A hundred-fifty plus will also quiet the piston a bit. Try to lock it into place or on a solid rest for the first few shots then prone, kneeling and finally standing to zero. Good luck

I cant answer that but I can say don't put this on an AR-15 after 2 or 3 rounds it is out of alinement after 5 rounds you shooting the target next to you its so off.

Ihave mine on a 12 ga as well, it hasnt exploded or anything yet, seems to be holding up fine to recoil,the mount is solid and it seems like a stout design, overall.

This device works great. I believe that you would have no problems at allI have a 15 gallon plastic barrel but am planning to use one of these and an immersable also. With metal it should conduct the heat better

It is incorrect. I purchased this for my DPMS Oracle and it has a low profile gas block. It is too tall for the high profile or handguards.

Ewl 30 is rated for -100 dg F . After our snowstorm south of Indy I took my AR DI wetted down with ewl 30, let it sit in -10 dg windchill for 2 hours, side by side with a open container of ewl 30. Then I proceeded to shoot 100 rounds through it with zero malfunctions over a period of an hour. And to that point the ewl in the open container still wasn't frozen. Beyond that I'm not sure

The barrel/slide end entends beyond the mount on my Glock .40 by about a half inch so there should be no risk of melting the mount. Though not mentioned, the mount sits high enough off the top of the slide on my Glock to allow me to utilize the factory sights. it is a nice piece of equipment, better than I hoped it would be.

What is really important is your psi Pressure machine. if yours is a gas pressure machine I do not recommend to use this, even if this one gun is a very high pressure. 1700psi.If your machine is over this limit or very close, it is better you do not use it. It could be damaged o broken

It is meant for a lower gas block. As I said in my review, this is a real piece of junk and I would never put them on any weapon of mine. I strongly urge you to save your money and get something better.

Shouldn't be a problem. Most lugs are mounted on the gas block, not the barrel.

Not very fast. Takes awhile to refill the tank. I guess you could to one bolt every 90 seconds. The duty cycle is pretty high on this, so overheating it should not be an issue.

You can mount it either place but mounting on the gas block will require you to raise the front sight post to account for the difference between gas block and acc. rail height. Mine is mounted on the rail.

Chances are the barrel diameter will be too large to accept this accessory. If you were able to make a fit, I would be concerned that heat from the barrel would ultimately compromise the part.

Yes, but the heat might effect the little rubber grippers inside the clamps (meaning melt them flat or otherwise) if you shoot it enough times in succession which might get the barrel hot enough to do so, I would think. Better to mount it on the feed tube magazine if you have the clearance. I didn't have the clearance, so I returned it.

I have had this mounted on my AK47, many shots down range. Less than 1" at 50yrd and less than 2" at 100 yrd. Friend mounted one on his AK with the same results, he just bought one for his AR15, and I'm getting one for mine. Several negative reviews out there, but I can't speak to other peoples installation/mounting or use. Mine and friends work great, holding up to AK47 recoil, multiple disconnects and banging around in /out of trucks. Still holding zero after 8 months. Buy it, price is good and it works.
