Description
The AGM Comanche-40ER 3AL1 Clip-On (AGM item 16C4O123453011, UPC 810027772428) is a night vision clip-on that mounts in front of your day scope fitted with a Gen 3 auto-gated Level 1 image intensifier tube with a green P43 phosphor screen. Gen 3 brings a gallium arsenide photocathode for high sensitivity in very dark conditions, and auto-gating rapidly cycles tube power so the image stays usable and the tube stays protected when lights or muzzle flash appear. Level 1 is AGM’s entry Gen 3 grade.

AGM Comanche-40ER 3AL1 Clip-On Overview
The Comanche-40ER is AGM’s extended-range night vision clip-on. It mounts to a standard Weaver or Picatinny rail in front of your existing day scope and turns it into a night vision sight with no re-zeroing, with capability out to about 1000 yards. It works with day scopes of up to 10x magnification.
AGM lists a 108mm F/1.54 objective with a 9 degree field of view at 1x, a weight of about 2.0 pounds (0.91 kg) and focus from 10 meters to infinity. It runs on a CR123A battery, or an AA with the included adapter, for up to about 40 hours.
Image Intensifier Tube
The 3AL1 configuration is the part of this listing that sets it apart from other Comanche-40ER versions: a Gen 3 tube with green phosphor. Note: photos show the Comanche-40ER housing, which is identical across tube options.
AGM grades its tubes by resolution and image cleanliness. For the exact resolution, figure of merit and blemish specification of the tube in this unit, check the AGM datasheet or ask us before you order.

Controls and Features
A quick-release mount lets you add or remove the unit in seconds, and a remote control lets you adjust it without taking your hand off the rifle. The distributor lists a 40mm exit pupil, matched to larger day scope objectives.
An included stray-light shield blocks light leaking between the clip-on and the day scope, which keeps the image clean.
What Is Included
The box includes the clip-on, lens cap, quick-release mount, output lens cap, battery adapter, CR123A battery, light suppressor, remote control, user manual and carrying case.

Who Benefits Most
This version suits hunters and security users who need Gen 3 low-light sensitivity, people working near roads, yard lights or flashlights where auto-gating helps, and buyers who like the classic green view.
Honest Limitations
Clip-on performance depends on your day scope: glass quality and magnification above about 10x reduce image quality. At about 2 pounds it adds noticeable weight to the front of the rifle, so check your rail space and balance.
Check state and local hunting laws on night vision and night hunting before you buy. Night vision image intensifiers are export-controlled and sold for use within the United States. Check AGM’s current warranty terms before you buy.
