I balked a little on the price ($95 + shipping) but all I can say is wow!
This thing is a little work of art, the machining is outstanding, this is a very complex part, VERY well done.
I love the way it places the light totally out of your line of sight, you cannot even see the light when looking through the sights or in your peripheral vision.
I have both an X300 and a TLR-1 and both fit and work perfectly.
The only shadow is from the BBL and is is very slight and well BELOW your line of sight.
I like this setup better than any other position, and I have tried them all.
Are you running a tape switch? If not, have you tried activating your X300’s momentary on after firing a magazine or two? :eek:
I ran one for a short time (even ran a temp test to see how well the x300 held up to the heat), but it’s in the spare parts box now. Maybe I’ll try another light setup with a more readily available tape switch; in the meantime I’ve mounted my X300 to the handguard.
Yep. There are 2 things I don’t like about the Hahn.
It’s barrel mounted and I’d need a tape switch… which I don’t like. The heat might not be an issue for a home defense gun… depending on what you’re defending against. And the price is a little high.
The only thing gained by the Hahn is that your light is less prone to banging since it’s 12 o’clock mounted.
But the Vltor and Vtac mounts hold G2 lights so snug in the 11 o’clock position, it’s almost a non issue.
lindertw- Thanks for the link to your post, I cannot find the link to your temp test or your other post that you refer to.
That post makes no reference to any problems you had with the setup, is there another post discussing the problems?
The LaRue aluminum mount would seem to me to conduct the heat to the light, where the stock plastic base would insulate the light from the heat transfer.
Is this the case? Have you repeated the test with the new LaRue mount?
I haven’t got to shoot mine yet, I hope it works well.
Demigod- I have the VLTOR plastic mount also, it is my 2nd choice and my backup in the pack.
I really don’t like it hanging off the side of the gun, is is a brush catcher where I use my gun, I use the muzzle to kind of “part” the bushes in my area, which is very forested (middle of the Ozarks).
here are some pics that were on my temp test post (had to reload them):
spots I took temp readings:
temp data:
X300 (factory base):
X300 + larue mount:
I ran the test to see what kind of heat to expect from a barrel mount, and if the light would hold up - it held up just fine.
My only dislike with the setup is that I cannot activate the momentary on function of the X300 w/out risk of getting burned on the barrel/FSB. Surefire makes a switched tailcap for the X200/X300 series, but it’s bulky, expensive and from what I’ve read problematic.
The LaRue mount was briefly installed, but I have not repeated the temp test as I don’t intend to run the Hahn mount. Should you care to supply 300 rounds of Prvi Partizan M193, I’d be happy to repeat the test w/LaRue mount so you can have the temp data
Wichaka is running a Pelican light w/tape switch on his Hahn mount.
lindertw-Thanks for all the info, that is a very informative post.
It looks like the mount isolates most of the heat transfer from the BBL with it’s design, as you know, it is free floated over most of the BBL, and only touches about 1/2" right by the sight base
I’ve got some black, self fusing silicone tape rated to 500 degrees F.
I’m gonna wrap the areas I might touch and see how that works out, I think it will insulate very well.
The tape only sticks to itself so it won’t leave a mess on the gun.
I ran it thru a rifle course back in July, when it was hot to begin with.
We ran 2-300 rounds in 4 hours, with breaks every hour or so. The light got very warm, but not hot. Also the tape switch worked the whole time, no problems.
I was concerned with the heat, especially after seeing the heat results, but after the rifle class…no worries now. I think if you were to run full auto bursts for a bit, or fire off many rounds with no breaks…it may heat up more, but for the average shooter and rifle class, it should be good to go.
I still love the location of the light…BUT, it’s too easy to burn yourself on the front sight/bbl juncture, your hand just naturally grasps the hot part when activating the light, so I’ll have to figure out some way to insulate this area.
Unless you are blasting off a couple of mags really fast, the heat is not a problem, it would be great on a Home Defense setup.
