Any gas operated firearm with a barrel port will suffer barrel erosion with use. My question is whether or not an adjustable gas block increases or doesn't increase barrel erosion compared to a standard gas block and if so is it even enough to be concerned.
Many manufactures over gas their rifles to obtain reliability with a variety of ammo. This can also have a negative effect on other operating functions of the rifle. The AK is notorious for this as are many AR rifles on the market. As the non adjustable gas block is used the gas port will erode more and more without any means of backing the gas down exacerbating the situation. If an adjustable gas block creates more barrel erosion than a non adjustable gas block how much more and is it enough to be a concern over the life of a barrel is the real question. Does using an adjustable gas block prematurely reduce accuracy life of a barrel compared to a non adjustable gas block and if yes how much? Do the benefits outweigh the negatives, does it matter in multi gun or could it be a concern with precision shooting? This would be a good experiment if it is thought to be a real concern.
