I guess a lot of it will depend on what you are looking for Carbine w/ 16 inch barrelLonger barrel? Adjustable stockA2 StockYes I looked into doing a build and by the time I would of gotten everything together it would of cost the same if not more than I got the one I have coming.Everyone says your can build one for less well as an exampleLower through a dealer in Wenatchee 225.00 then the parts kit another hundred $325.+Then you start adding the cost upper and barrel together $600.+Sub Total $925.+then add your tax, FFL and dealer fees you're looking at a grandIMO I could not see putting one together and being able to save any money over just purchasing a factory built at least not one with any quality. Oh I'm sure there are some out there that I could purchase for less than what I paid but probably like the one a friend got for around $500.00 then took back the next day because it was jamming big time.I Shopped around and got the Stag Model 4 for $200+ under what Stag is advertising them for on their website if I'd of bought the lower and upper separate and put it together myself and almost $300 less than their Assembled Model 4. I went with Stag for the name, style, lifetime warranty and guaranteed accuracy out of the box......Sure I have to wait to get it but when I do it is coming from out of state and private sale.....
