Product Overview

GL4 Pro Laser (Defense Distributors Edition) – Compact IR Laser + Light Combo

The GL4 Pro Laser – Defense Distributors Edition is a purpose-built infrared laser and illuminator unit designed in collaboration with RovyVon. This exclusive version refines the original design with critical upgrades: better QC, corrected markings, and hardened internals — all based on field testing and real-world shooter feedback.

This is one of the few compact laser/light units on the market to offer all four major outputs: a visible green laser, infrared laser, infrared illuminator, and (on select models) a white light. It's ideal for shooters running compact rifles, suppressors, or setups requiring a wide, even flood in a tight package. When size, price, and performance all matter — this is the unit to beat.

Key Features

  • All-in-One Configuration: IR laser, IR illuminator, green laser, and white light (on Standard & XL versions)
  • Built-in IR Indicator: Lets you know when IR functions are active — no more guessing
  • Improved Fire Controls: Ergonomic switches for both momentary and constant-on use
  • Upgraded QD Mount: Tool-free attachment with reinforced recoil lug (V3 variants)

FAQs

Q: What makes this version different from the standard GL4?
This Defense Distributors edition features reinforced adjusters, improved laser output specs, and proper markings. All units are final-QC’d in the U.S. to meet our standards.

Q: Will this mount to my rifle?
Yes — it mounts to any standard 1913 Picatinny rail using the built-in QD mount.

Q: Can I run this with night vision?
Absolutely. The IR laser and IR illuminator are optimized for NVG use, including close-quarters flood and long-range aiming (XL variant recommended for distance).

Q: Is this a PEQ-15 clone?
No — the GL4 Pro is its own platform, purpose-built with a different form factor and philosophy. But it offers similar functionality for a fraction of the cost.

    Great value

    Posted by Ryan Ringo on Feb 10th 2025

    This is a good value for the money and is great for a smaller AR/AK where you don’t want a huge lad on the hand guard. It does everything the review prior to mine states so I won’t repeat all of that, what I have been most impressed with beyond the unit itself is the quality of customer service I received from Defense Distributors. I run my equipment hard and I had to send my unit in, and their customer service and support is absolutely second to none. I recommend them to all of my friends and only wish they had an even larger inventory because I would shop with them first at this point over the usual larger online stores we all frequent. These guys are top top shelf.

    Amazing laser for price

    Posted by jjarv537 on Jul 25th 2024

    I am very impressed with the gl4 pro. I had been searching for a light/laser combination for my mp5 and finally bought a surefire xvl2-irc. It broke the first time i tried to sight it in and after repairs were done by surefire it broke again! so imagine my surprise and shock when a $350 Chinese light/laser worked and beat a $1300 surefire light/laser. THe good: 1. It is inexpensive (not Cheap) 2.the lasers are slaved so you can sight in during the day and your ir beam is sighted in as well. 3. it holds zero. I tested it for 4 weeks going to an indoor range and shooting on a rest at 25 yards. the groups remained the same and even removing and reattaching the gl4 barely moved the group. I only had to adjust 1 click to bring it back to zero. 4. compatible with surefire accessories. I have the surefire rsr-07 tape switch mounted with a magpul M-lok tape switch mount. the pressure pad does have momentary or constant on depending if you press or hold the pad. 5. changing modes is easy but secure so it will remain in the mode you prefer. there is even a diagram on the unit if you forget. the bad: 1. the light (vis and ir) are not as strong as i would like but are adequate for 100 yard use. which for a 9mm mp5 is enough. 2. the initial clicks were mushy and hard to feel but after 2-4 clicks they became easy to feel and hear. conclusion: for the money the gl4-pro can’t be beat if you are looking for a 100 yard visible/infrared light and laser unit. the gl4-pro is right at home on a pistol caliber carbine or sbr. the unit may even be able to upgrade in the future since removing the head with the white and ir beams is how the battery is changed. if more powerful heads are released the end user can change it at home with no special tools needed.
