I have 3 1000 rnd Bulk Packed cases of Remington UMC 223 55 grn FMJ Ammo for sale. This is new unopened Remington UMC ammo. I will sell for $300 each Shipped.
I have AR15's with Magpul PRS and Luth AR stocks. Both are good but I prefer the Luth AR stock over the Magpul. It's more comfortable, lighter weight, and costs much less. I got mine at Armscomp.com
Luth AR Stocks
I have a badger bolt handle on mine. The badger works really well. It is an easy modification that you can do yourself. All you need is a bench grinder, hand file, and threading die. The badger bolt knob comes with instructions.
I have the Nikon 4x16 tactical and several Leopold MK4 scopes. I would put the Nikon far above the leupolds for clarity, sharpness, and repeatability. I just wish they would make it with 1 moa elevation adjustments like the Leupold MK4 M3
