Hinged gas block?

[coolarthur1]

I have a pinned and welded barrel, are there any hinged gas blocks that I can use? Usually un-pinning the muzzle device destroys it and I don't want to ruin my Surfire socom brake.

I know there is a YHM hinged gas block but its out of stock everywhere. Any other options?

JP makes a 2-piece adjustable block:

Bolt together gas blocks limit your options on rails as the bolt together ones don't fit under slim rails.
Also, the cost/effort of cutting off a gas block and then buying a bolt-together gas block is similar to replacing a surefire brake.

If you have to replace a rail to fit the bigger gas block, then it's cheaper to cut off the surefire brake.
