I am new to AR 15 but have 10 or 12 WW11 rifles so I have been more of an old gun collector. Me and my twin boys are nearly finished building a Romanian AK 47 which proved a little harder than I thought it would. Anyhow I wanted to do a 1911 colt pistol build but boys want to build an AR 15. I have bought an upper Del-Ton and should be receiving it any day. After doing some research on AR's which I know nothing about I found Spikes Tactical is 8 miles from my house in Apopka. I need to buy a stripped lower and like the look of Spike. Since I would save freight and FFL are there stripped lowers considered pretty good? Now that I have done more research I am going to unload this one pretty quick. Next time I just want to buy the barrel and really start from scratch and get a truly customized AR. Like I said with the savings on FFL and Freight would a Spike be a good choice? Also what is a Tax Stamp?
