    Just in case I decide to field strip my weapon while blind folded in the dark, you know like we all did when we were Privates.

    I recently purchased a Stag Tactical 15, quality weapon, well built. I don't see having any issues with it, but decided to grab as many spare parts for it as I can. At least the ones I can get my hands on. Just in case I ever need to replace parts for wear and tear. I'll be grabbing more spares as they come back in stock. I'm sold on Stag Arms and what they have become, longterm customer from here on.

    Small parts (spare just in case) needed for rebuild. Good quality, no nonsense parts. Thanks.
