Question for those who've actually worked with the Hahn and the SideArmor:
All of the pictures show them used on barrels with conventional FSBs. Will either of them work with barrels that only have a gas block on them?
I'm predisposed to the Hahn due to cost and SideArmor's recurring refusal to admit there are Left Handers on the planet.
... but I'll go with what will work for my barrels. Thanks.
Yup, I'm a Dinosaur!
Unfortunately, the Hahn Precision forward light mount that I bought didn't fit properly on the Noveske N4. The Vltor Vltor 10" VIS monolithic upper length positions the forward light mount where the barrel diameter is narrower so it would just spin around the barrel. I was able to use it on another AR with a fixed front sight and it works perfectly.
Is anybody using any of these barrel or FSB mounts on a SBR? I was just wondering if there is enough room for them with such a short barrel.
Pics would be great if available. Thanks.
Something that I have noticed with the light at the 12 o'clock position is that if you are running a suppressor, you will have a huge "butt-plug" looking shadow on the ground. I would think that one will find way more threats lying on the ground than lying on the ceiling if the light were mounted in the 6 o'clock position. Just something to think about, everything is a compromise.
The mount somebody showed on the previous page is the ILM and the pictured version is available. Upside, it does not clamp to the barrel, if that's an issue with you. Downside, I need the FSB (or complete upper) so I can mill a little locating pad for the rail and tap a hole for the cap screw that holds it on.
The clamp-on version I had on my site is back-burner unless somebody big comes along and want to cut a PO for a bunch of them. I think it has a lot to recommend it but it's complex to machine and therefor expensive.
I have some other designs that are proven and I've done several of..... production and availability are coming soon but not sure when-- so many irons in the fire. The "ILM-JT" is shown in this thread. The silver-solder-on version is really more sanitary looking but just not viable as a production item, custom only really, and as FSB's are married to barrels, when the barrel needs changing there's a complication.

I have an idea...gimme a chance to plug it into Paint or something to describe it better.
Basically you get a QD type mount to attach to the end of the 3 or 9 o'clock rail. It then goes fwd and extends past the FSB or just out in front of your rail if you have a FRONT BUIS.
From there it would curve up over the barrel w/ another rail in which you would have somewhat like what Ned has been doing.
Just a thought...I have absolutely no machining skills however so I have no clue if it's even possible.
Or possibly a two piece mount w/ a half on each side that attaches to the 3 and 9 o'clock positions. Then the two pieces meet up above the barrel, out front of the FSB or rail. There wouldn't be much of a need for a clamping screw I don't think, due to the light holding the end together.
I'll work on some paint pics in a bit.

ATTENTION: What you just read may very well contain sarcasm! Judge me accordingly.
Sorry if this has been discussed before, but is there a 12 o'clock rail mount for lightweight barrels? Im looking into getting a BCM lightweight midlength upper and would like to mount a Streamlight TLR 1 in front of the front sight.
Thanks
