Are they created equal?

Building a rifle with no FSB and a rail-covered gas block and I'd like to know if I would be good going with something from YMH (~$25) or if I'll benefit from getting it from a costlier manufacturer?

Thanks!

I got a YHM set screw low profile gas block last spring. It was out of spec and would not fit my barrel. I would get a clamp on Daniel Defense if i were buying one today.

You answer just about every question I post - I think I'll need to get your email address ha.

I used YHM just as an example of a block that was in that price range.

I bought the YHM and have had it for at least a couple of years with no issues.  It was extremely tight when I was putting it on but it hasn't moved and it works well for me.  I can't speak to the others, but I would say that they are largely created equally.  The only thing that the gas block does is redirect gas (a very important but simple task).  As long as the gas ports are lined up correctly you are good to go.

I've used Brownells, YHM, Sadlak, and made my own gas blocks from pinned FSBs and none have given me issues. The tricky part is aligning the gas ports but putting masking tape on the  barrel and marking directly behind the port gives me a place to line to. I also use a halved handguard cap to give proper spacing for it in case it needs that clearance so the gas tube doesn't go too far into the receiver.  Used on Wilson Combat 6.8, Satern 6.5 Grendel, and other barrels I've built uppers on.

I have used cmmg and Larue gas blocks.  I prefer the Larue gas block myself.

YHM low-pros are g2g.  The clamp-on is of course my preferred type.  Take the screws all the way out and you'll have no problem placing it on any .750" barrel.  Torque the screws back down for a strong tight fit.  Put many rapid rounds down range for the purpose of testing the fit on mine.  I have been pleased.

This is the one that I use.

Had a bitch of a time finding a decently priced clamp on that was in stock.

Ended up scooping a MI for about $45 shipped, so all is well! :D

Can't say we've had any customers come back with any fitment issues that we are aware of with any of the YHM gas blocks, at least in our experience.  We had one fluke that popped up however. A YHM "slotted" gas block was not "slotted". For whatever reason, it didn't get the final cut to actually produce the slot. Not quite sure how that made it through QC, but it was apparently the first one of it's kind that YHM had heard of.

Ok so my dumb ass accidentally ordered a normal screwdown gas block instead of a clamp on like I intended to.

Should I go about returning this one or just deal with it?

It's long like that to cover the area where a fsp might have been.  

I prefer the VTLOR lpgb as it fits my pinning jig.

Since you have the option of returning it, I would.  If you want to keep the set screw gas block, it can work just fine.  The trick is to dimple the barrel where the set screw hits it.  Easy to do and will ensure that the block never moves unless you want it to.  Simply get the block in position, and use a transfer punch to mark the barrel where the set screw will go, then use a drill bit to put a shallow dimple in the barrel.  Locktite and tighten the set screw.  Piece of cake.

Blargh.. I'll go ahead and eat the few bucks for the return/handling and order a clamp on.

Thanks!
