Up for grabs... A Colt SP-1 lower receiver with an SAA M-4 upper in unfired condition. The rifle has a full compliment of Magpul products, an ACS Buttstock, MIAD pistol grip, an AFG foregrip, MOE handguard with rails, and MBUS sights. The rifle is in excellent condition and ready to go to its new home. Hate to see it go but I'm going a new direction with my collection. $1,000.00. Shipping is not an option.
