Malkoff SIR 700

What it is

• Dedicated IR only head (no white light) that threads onto Scout‑pattern 300/600‑series bodies (Arisaka and SureFire M300/M600, plus similar hosts).

• It is the high‑output sibling to the SIR/EX IR 250 head, using the same ~5° optic but at much higher power.

Key specs

• Output: 700 mW infrared, 850 nm spectrum.

• Beam: 5° tight beam angle; described as exceeding a PEQ‑15 at high output at equivalent focus, with strong mid‑to‑long‑range reach.

• Runtime: about 1 hour continuous on a single CR123 cell.

• Power options: can use one or two CR123 cells or one 16650 cell depending on body.
