Why Units Asked for Them

First posted on this blog in June 2012.

We are getting tons of government orders for scope rings. Many Soldiers and Marines in Afghanistan are buying our scope rings for their designated marksmen and snipers. If your unit needs some good scope rings, just tell your supply sergeant, company executive officer, or company commander that you need them and give them our NSN listing which is at this link. Below is a list of our awesome scope rings and their National Stock Numbers. You can also get them on the GSA Schedule GS-07F-0144X.
