Therealkoop Posted December 16, 2013 Share Posted December 16, 2013 Yup. It doesnt move, at all. Id like to turn the gas down a bit now that I went from a FA to a lightweight carrier but its not happenin'. The allenhead is so small that the tool just want to strip it instead of move it. Anyone else having issues with it? I emailed Syrac a long while back but was never responded to. Actually a thought just dawned on me while typing this, I'm going to magdump a whole hell of a lot of rounds and get it piping hot, then try again.

Pat Miles Posted December 16, 2013 Share Posted December 16, 2013 Why waste the BB's, pop the handguard off and heat the block with a torch. No reply from Syrac? Hmmm. Pat Link to comment Share on other sites More sharing options...
MarkCO Posted December 16, 2013 Share Posted December 16, 2013 That is not that uncommon with adjustables. Heat won't fix it either. Muzzle down, squirt a little CLP, FrogLube, or other "thicker" solvent down the gas tube and let it sit for 24 hours. I used to just take the gas block off and put the comp and the gasblock in a bottle of CLP for 24 hours. Rinse it out and try the screw. The threads get gas cut, then filled with carbon and some copper and if you do pull it out, it can damage the threads rendering the block useless.

jmfs21 Posted December 16, 2013 Share Posted December 16, 2013 If what mark says doesnt work then take it over to Doug Jones at Accu-rail in rochester. He will be able to get it out for ya. Call me if ya need his info. Thanks, John Link to comment Share on other sites More sharing options...
openclassterror Posted December 17, 2013 Share Posted December 17, 2013 Ultrasonic brass cleaner. Just don't leave it in too long, or it will strip the finish or eat the screw...... or so I've heard Link to comment Share on other sites More sharing options...
bmiller Posted December 17, 2013 Share Posted December 17, 2013 I had one seize. I sprayed Kroil down the gas tube while standing the rifle muzzle down. Applied a few times and it loosened up. YRMV. Link to comment Share on other sites More sharing options...
Therealkoop Posted December 17, 2013 Author Share Posted December 17, 2013 Thanks guys Ill try the gas tube route. I tried putting it on the opposite side of the block but it probably had poor penetration. Link to comment Share on other sites More sharing options...
TRUBL Posted December 17, 2013 Share Posted December 17, 2013 Aluminum gas block??? soak it in Wyndex glass cleaner. No kidding......little trick I've learned about aluminum that seizes...this works better than oil. I've used it on aluminum/aluminum and aluminum/steel FYI....This little trick will work ANYTHING aluminum that's stuck.....not just aluminum gas blocks.

Mturnbull333 Posted December 17, 2013 Share Posted December 17, 2013 Won't believe it but redbull will loosen up anything, actually kinda scary considering all the jäger bombs I've consumed! Link to comment Share on other sites More sharing options...
MarkCO Posted December 17, 2013 Share Posted December 17, 2013 Just an FYI, Windex has ammonia in it. The reason it will loosen seized AL is because it puts the protective oxide layer into solution. You would essentially be removing a small layer as well as creating some slight pitting. That layer will then reform once the ammonia is gone and it is in contact with air for a while. AL/AL interface essentially shares a protects layer thus the bond strength can be pretty high over time. This is why we anodize AL. That formed oxidation layer is much tougher than the formed layer due to exposure to air. AL/SS creates a degrading galvanic corrosion cell and is one of those interfaces that design engineers need to be careful with. Link to comment Share on other sites More sharing options...
Finbox Posted December 17, 2013 Share Posted December 17, 2013 My Syrac block froze up and it was because the adjustment screw was cracked down the length of it. Call Syrac...their CS was a joke...3 mouse clicks and brownells took it back, it was 10 days new Link to comment Share on other sites More sharing options...
Lead-Head Posted December 17, 2013 Share Posted December 17, 2013 How about take that GB off, replace it with a reg GB, and never have this problem again. Link to comment Share on other sites More sharing options...
Therealkoop Posted December 18, 2013 Author Share Posted December 18, 2013 It still shoots fine, I just want to turn the gas down. Id rather not run balls out on the gas with a standard GB. I suppose I could get a barrel that has a smaller gas port. Link to comment Share on other sites More sharing options...
Doug H. Posted December 18, 2013 Share Posted December 18, 2013 (edited) My Syrac block carbons up and can't be adjusted with the long tools that came with the block. I usually have to take off the foreand and use more torque to adjust it. I like the system, but it's not good if you want to make frequent adjustments like between suppressed and unsuppressed operation.Doug Edited December 18, 2013 by Doug H.

Therealkoop Posted December 18, 2013 Author Share Posted December 18, 2013 Looks like the kroil down the gas tube might have done the trick. It definitely turned a few turns but its still pretty tight so Im going to give it a second pass. Thanks guys. Link to comment Share on other sites More sharing options...
Jesse Tischauser Posted December 22, 2013 Share Posted December 22, 2013 (edited) My Syrac locked up too. I'm now installing the cool Seekins Precision field adjustable gas blocks.

With a clamp on you get a tighter fit that is even throughout the circumference of the barrel so it basically fits up tighter and seals the gas better. Also no need to dimple the barrel for proper installation. They are easier to remove if needed, as quite often you will get a burr under the set-screws. I've also read that set screws can also add a stress point to the barrel. That said, I've never personally seen a barrel pick up accuracy from switching over to a clamp on block, but the concept seems valid. With the set screws your gas block is attached just with pressure on the top and the bottom, so as the barrel and gas block heat up I can see how things might move around.

I wouldn't mind if they didn't leak that's for sure! Link to comment Share on other sites More sharing options...
