YHM Specter gas block install question

This is a 2 piece clamp on gas block. I got part number 9378 for a .750 barrel and I have a Daniel Defense stripped barrel with a .750 diameter. Once installed the gas block does not sit flush with itself on the sides. It makes full contact with the diameter for the barrel but i cant tighten it anymore and there is a gap on both sides. Is this normal for a clamp on gas block?

Yes this is normal. 2pc gas blocks are less than ideal.

thank you. im gonna loc tite the screws and hope for the best.

I suggest Rocksett.

Where can i get Rocksett? Google can’t seem to find a place that sells it. I found this stuff on amazon:confused:http://www.amazon.com/Flexbar-Rocksett-2-OZ/dp/B001C1D800/ref=sr_1_1?ie=UTF8&s=industrial&qid=1267932435&sr=1-1

That’s the stuff.
