Recommendations for a low profile gas block, .625" shoulder diameter, one that slides off and doesn't have any tight fitment issues...
This is for a voodoo barrel. Thanks. |

Actually I was looking at the DD clamp on too.
It needs to fit under a Fortis rail. Here are some choices I found... Gas Block: BCM LGB .625 @ $45 Gas Block: DD Low Profile Clamp Style - .625 @ $61 Gas Block:Syrac Ordnance .625 Adjustable Low Profile @ $96 Wheres that spikes .625 at.. link? |
| Syrac and SLR both have new generation adjustable gas blocks. Check their threads out here. |

Must order gas block... I have a barrel to install!
I am super super excited and very impressed with this Voodoo EVO ultra lite barrel. All I have to say is WOW. Beautiful... very light. Super impressed. Did a mock up... I estimate the weapon will weigh 5.7lbs unloaded! 5.7lbs including a Sb15 brace!

There is a huge misconception that the dimple is needed to hold a set screw gas block in place and nothing could be further from the truth. The fact is the dimple only makes lining up the gas block near fool proof. If you install a set screw gas block correctly it will not move. The dimple does not hurt anything, but it sure as hell is not mandatory if the installation is done correctly. Clean the screws and threads with acetone and then a half-drop of BLUE lock-tite on each screw. Tighten securely but you don't need to gorilla it in there. Let it set up and you are done. I even have a set screw gas block, a high rise type too, on my .470 Rhino and the barrel was not dimpled and it has never moved, and it has the recoil of something like 4 .308s all going off at once. If you install a set screw gas block and it moves, you installed it wrong, period.
However, I love the dimples because as I said, you just center the set screw up in the dimple and screw it down, perfect alignment every time. With no dimple you need to do some measuring which is not rocket surgery, but you'd be surprised how many people screw up their gas block installation by just slamming it on there and calling it good, then wondering why it is short stroking. |
