Hi guys,
as the DD Omega rails are quite tight on the inside, I wanted to know what LoPro gasblocks will fit under the Omegarail without having to modify it?
Inparticular interested in the fit VLTOR gasblock and 12' Gasblock.
Thanks !

Notice gotm4 said "nearly". He posted pics of a gas block he made out of a standard front sight base that I believe he said fit under the Omega. It looked like a lot of work, and he mentioned a lot of tools he used to do the job right.
And that is why he ended with "impossible" ;)
Yep....it's just not worth the effort.
If I had charged for time/labor that would have been a $200 shaved FSB. It was that much of a pain in the ass.
That was a FSB on a .625" pencil barrel (14.7") with a perm. attached A2 flash hider. I had to grind and mill on it while it was still attached to the barrel. .750" barrel? Forget about it!
thanks guys !
is the RIS II also 12''?
Juan, how does the Vltor compare to the stag arms / pri lopro blocks?
thanks
Venom, just wanted to let you know I've got a pri gooseneck gas block on my omega 12. With a dremmel and about an hours worth of work I've got a great set up.
For what it's worth - I just installed a DD Omega 9.0 on my BM carbine, went with a CMMG .750 Micro gas block (per DD's recommendation) and it all worked out well.

I did a mock up of a 12" Omega and a Noveske/Vltor gas block on my Afghan barrel. The fit was too tight for my comfort. As I recall, the top of the rail wasn't the big issue, the area near the pin and set screw was really close to the bottom rail. I wish I had taken a picture. Fit was perfect with a Lite rail, plenty of room.
Contact between the gas block and barrel will cause erratic vibration which will in turn cause weird accuracy. You might not see it at 25yds but you sure as hell will see it at 200yds+. That 10-15 thousands clearance between the gas block and rail/FF tube seems okay until you actually shoot the rifle at some distance.
I'm may be wrong, but it seems like it has decent clearance to prevent contact.

Can you make the rail smack into the gas block? I'll bet I can.
There's a reason why RISII and Lite Rails have much bigger and stronger bolts holding the rails in place.
It's because people like me who run shit very hard and have broken, bent stuff.
I wouldn't trust an Omega rail mounted with it's four small allen screws to keep the rail from hitting the gas block when the gun is run hard. The Omega is a fine rail for what it is. It wasn't meant to cover a gas block.
Yeah, I'm sure I could if I tried, but I think I could make any full float hit if I tried hard enough.......that's why I'm still not 100% sold on any of them yet.......
I took a stab at shaving my FSB over the weekend and decided to switch to a DD Lite 10.0. Not sure if I've taken it down far enough yet, guess I'll find out when the Lite arrives and break out the grinder again if need be. I ended up taking about 1/8" off the taper pins to get them to match the new profile.

Yep, I did some searching and found a lot of the info you've posted up on shaving GB's.....I can say you're definitely patient person because you've taken the time to answer the same question over and over several times over the years :)!
Anyways, I ended up taking about 1/8" off the large end of the taper pins to get them to match up with the new profile.
After reading some info you posted on installing the DD Lite a long time ago, it sounds like it could be really fun getting the taper pins installed through the handguard without a starter tool........I may have to fab something up while I'm waiting for the rail to arrive.
Got it all finished up. I shaved my gb enough that I was able to pin it in place and then slide the rail over it.
Good information. Saved me a headache.:D
What about this issue on a Omega X rail?
nvm I see where it was hanging up:o
