Sionics 11.5 barrel w/ reduced gas port function report.

[mtdawg169]

Yeah. There'd be an unsightly gap without the handguard. I wish Geissele had made the rail longer so the cap could be removed. Makes no sense since you have to pull the FSB anyway. But I still like the rail.

If they would make a 10 or 10.5 rail again, I'd never use anything else.

The standard port 11.5 barrel shoots good as well. I was able to get my KAC RAS to fit mine, just took a rotary tool to the front clamp to make it match the profile underneath the front cap. You don't need to take a lot off, just need some patience.

I was thinking of doing that, but worried I'd mess it up. I couldn't decide on the risks of lathing the barrel (which I can't do myself) or permanently modding a RAS.

I have two of these barrels and I’m trying to figure out my bolt carrier/buffer combo. I plan on running VLTOR A5 buffers, Sprinco green springs, and A5H2/A5H3 weights.

These rifles will be ran both suppressed and unsurpassed. I’ve read about all the LMT Enhanced carrier hype, but I tend to stick with either KAC sand cutters or the JP full mass carriers. Anyone running any other carriers aside from the LMT with similar setups? Thoughts?

At danger of angering the necropost spirit...
I’ve run this setup with a BCM phosphate carrier and a Sionics NP3 carrier. Functioned fine, though a little gassy in the face when suppressed. I think I was running an A5H3 buffer with green spring...

I dont even know the heavier A5 buffers, I played with them but feel the standard are the best. I tend to feel the buffer slamming back on the heavies. The A5 is more important than the Enhanced BCG, but both dont suck. KAC stuff is always good.

I am running the RGP with an LMT E-Carrier, Sprinco spring and A5H4 buffer. Which means a standard carrier group will be just fine with your H2/H3.

Because these barrels are gassed correctly, its no magic equation to make them run. A lot of different combos will work, hence the beauty of the Sionics RGP barrel.

In that case, ordering some of the Sionics BCGs to go with them

Agreed.

Being the OP, I suppose I should note that mine is STILL running with such boring reliability, that I forgot to post about it. Too busy actually shooting it, I guess.
