Actually worked on 2 of my Rifles Today.
For the AR15, I put on a Millet Tactical 1-piece 30mm Scope Mount, while waiting for a (New) Bushnell 1-4x24 w/BDC Scope, that's currently on Layaway. Also mounted a 45* Mount for a Holographic Sight that I will be purchasing in Future. Also got a ProMag 5Rd Magazine---just because.
For my other Rifle, which is a Hi-Point 9mm Carbine(995TS), I purchased 2 more 10Rd Magazines, and attached a Dual-Magazine Holder onto the Butt Stock, that's a Factory Accessory, so now I'll always have 30Rds with me instead of 10. Also installed a Center Point Lazer for Nite Shots at Varmints on the Farm. I have a Tru-Glo Red Dot on it, but now I'll have a choice, when the other doesn't work as well. Need to also get a cheap, but good Tactical Light soon. Looking/thinking of those NEBO Lights and a Mount at WalMart, but still deciding.
Just good Back-Up precautions.
