A salesman, no. I'm sorry I didn't see your post. As was said above, I was just suggesting an actual fix to the problem rather than a bandaid. My mistake for proposing doing the job the right way. I had an overgassed gun and went with the adjustable gb b/c it seemed like less hassle than wasting time ordering buffers that may or may not work and it corrects the issue at the source of the problem. If youre not confident in changing a gas block, thats fine, but you don't need to get all dramatic on us. I'm sure you've skimmed over or missed posts in threads before.
