    poor service after sale

    Posted by Daniel on Oct 27th 2017

    I received my thorn tail and upon installation found out the bolts were too long. Tried calling several times. Wasted an entire day with emails and finally told had to contact the manufacturer for help. Spoke directly with him at 9pm and problem resolved. Great product but next time I will order direct.

    Flashlight adapter for Ruger 10/22 picatinny rail

    Posted by Thomas Ferrell on Nov 11th 2015

    Talk about fast service. Had it in two days. I didn't know what I needed and BC worked with me for two days and came up with a suggestion. Unfortunately, it didn't fit my particular flashlight and when I sent them a pic of the issue they promptly sent me a return authorization. Good people to deal with. I may just email them again and see what else they may find for me.

    IWC - Thorntail Mount & Customer Service

    Posted by LF on Nov 27th 2012

    I purchased this product to mount my Eagletac T20C2-MKII to my BCM Mid16-Mod 2 carbine. The mount is well engineered & a high-quality product.

    Although my Eagletac is spec'd out at a 1.0" body diameter, the supplied ring didn't fit properly. The light body is slightly larger. I emailed IWC and their staff responded literally within minutes. Earl assisted me and resolved my problem by shipping me a new 1.030" ring and hardware (at no charge).

    Impact Weapons Components and BCM ... Two top tier companies with absolutely outstanding service & support! They will continue to receive my business and hopefully yours. Thanks Earl & Paul!
