    Accessories L3 RULR - Full Kit

    I will note that these are really great rangefinders, 1570nm laser with a 1 mil divergence, 99% detection of targets < 2500 meters +/- 1.5m and under good conditions can ping a target at 9000. Wireless remote button and a remote display make this really handy for a spotter/sniper team. When...

    Suppressor Issue

    I've seen this issue, but only with handloads, not factory ammunition. If a powder is used that does not get a complete burn in the barrel length available, the excess powder and gasses can flash over in the suppressor, leading to a VERY high pressure wave going back down the barrel. The old...

    Trip to the "Desert" - OR - Oh That Insane Mirage

    As it happens, we just did the XLR class last week where I explain this exact problem and show some video. This is why I don't advise clients to bring scopes over 25-27X or so, we often need to shoot closer to 20x anyway. Understand, you don't actually see the target, you see an IMAGE of the...

    Night Vision Vortex Impact 4000 Rifle/Rail mounted Range finder???

    Honestly, unless you only own 1 precision rifle, I can't see doing anything other than mounting it to the spotter. Who wants to remount and rezero the thing everytime you change rifles, and who can afford one for each rifle?

    Night Vision Newb looking for clip-on advice and info

    One can generally rely on the manufacturer saying it has a clip on mode. If they don't, it does not. As stated, they need to be 1:1 at 1x, and have some way to align the screen.

    Night Vision Newb looking for clip-on advice and info

    1 Day optics are compatible in that the magnification range must work with the selected thermal device and mount high is within range. 2 For a thermal to act as a clip-on device, it must have a true 1:1 output mode and either a lens system ot screen alignment mode to get a boresight zero. 3...

    Vectronix Bluetooth Adapter

    Anyone happen to have a Vectronix BT adapter for either the Vector IV/PLRF or the Vector 21 that I might borrow for a bit? Need a unit to test code for Field Firing Solutions and they appear to have gone out of stock everywhere. I could also use a PLRF25 BT early non-AB version, but that's a...

    Field Firing Solution (FFS) new Android release?

    OK, import of a KML file for targets and FFP's in now on the list. That should allow for integration to ATAK or Google Earth for targeting.
