Ow adj. gas block - ODIN Works Tunable Low Profile Gas Block

Ok, its nice to look @. It was simple to install. But it leaked something awful. I already had a standard stainless gas tube, didnt see any reason not to use it. Odin Works did not recommend using one of their gas tubes, nor did they specify any caliber. It leaked badly all around the port in the block. The port in the block is too small. I was an armorer and know what im doing. That said, some folks gave it a good review. Maybe they don't know theirs are leaking.
