This is a used Millenium M500A series white light forearm for the SIG 551 series (and can also be used with the Sig Sauer 556). This came off of an ex-PD rifle. It is used with some exterior wear. There is some standard gunpowder staining of the bezel where it sits next to the gasblock vents. I also inadvertently broke off one of the "ears" on the top/right/rear of the handguard where it interfaces with the receiver while trying to install it on a Sig 556 with an out of spec rail. I epoxied the piece back in place. It is very small, approximately 4x6mm, and is cosmetic only. Functions 100% with blue LED running lights. This is an awesome light for the 551/556 series.

Price is $265 shipped/insured. Payment must be US Postal M.O. or personal check, however personal check will have to clear my account before shipping. Email me at jsurowitz [at] aol [dot] com if you are interested. First email stating "I'll take it" gets the light.
