The guide can be gotten at alot of different places on the web.The stripper clips are AR15 or M16 stripper clips.One source is
www.clipsnstuff.com,or try tapco,cheaperthandirt,deltaforce,
www.chestnutridge.com has new stripper clips at a fair price.I used to have a URL before the putter crashed 2 months ago with a place that sold a whole recharging kit for near nothing,and some people were putting them up on EBAY for 300% more.I'll look around and see if I can find it again.You might try army surplus,magazine links.Via any of the larger search sport databases,such as
www.gunnery.net/links or shooters links etc.
