7.62x39 Compatible (19/05/2018)
I actually purchased this for my AR15 762X39. It works great.
Excellent Product(20/10/2009)
Nothing to it, fits in the chamber perfectly, guides the cleaning rod, o-rings seal up the chamber very well. Excellent product, wouldn't clean an AR15 without one.
Great cleaning aid(28/03/2010)
Works great and keeps your jag /loop or rod end from hitting throat area. Keeps everything out of the chamber and lugs very good tool.
I would buy this product again.(27/04/2011)
Works well. The only fly in the ointment is the "O" rings break, but from what I can tell that's a common issue among most or all makes of bore guides. They do include many years worth of spare "O" rings and a device that makes it a snap to replace one. I highly recommend this guide and would buy another to replace the one I have if I lost it.
Nice tool to use(07/09/2017)
Nice tool to use if opening AR like a shotgun to clean from chamber. It does keep solvents and oils out of trigger housing.
good product(17/10/2015)
The fit and finish of this product is clearly top notch. Be aware that it does NOT fit DPMS G2 rifles; Dewey makes a special model for these (AR-DPMSG2).
