How do I replace the gas block, I have an SAR-1, and would like to get the bayonet lug back on but how do I replace the gasblock, do I just drive out the pins and just slide it off, or will I have to use some sort of hydrolic press or simular, same goes for putting the new one on do I just slide it on and pin it in place or does it requir a press, also will the new gas block have the holes pre-drilled or does it have to have new ones drilled?....

Are the pins taped or can they be tapped eighther way, and the same questions apply to the front sight base as obviously that will have to be taken off to work with the gasblock?....

Is this something I can even do myself I only have basic handtools available, or will I have to have a gunsmith do it, what would be a decent price for a gunsmith to charge, and where can I find replacement gas block, prefferably Romanian, or should I just switch the whole barrel, assembly with a non-neutered one, and who sells complete Romanian barrel assemblies?....

Is there an easier way to restore the bayonet lug, and have it be correct?....

Hmmm, you may have a problem finding a block that will work, the problem I see is that the gas port and the pin holes need to line up on the new block otherwise when you redrill the pin holes they'll end up being elongated and the block could move on you. I don't know of any Romy 90 degree blocks out there, you might try the EE. You can't just use something like a Bulgy one because the gas port hole and pin spacing in the block isn't the same dimensions as a Romy.
Maybe email Troy Sellers at In Range: [email protected], jnewt may be able to tell you something too ...

Are the ears just ground off, or is it really hacked up? If it's just the ears, you could get a welder to spot some metal back on where the ears used to be, and some creative use of a dremmel tool might work...it could be worth a try rather than replacing the gasblock...I would replace the gasblock as a last resort personally....there are guys here that would dissagree, but you will have to remove the front sight to do the gasblock...alot of work if it's straight now, it's hard to justify removing it unless it's your last resort...just an opinion here. Good-Luck.
