Shipping Info We ship all items in 1 - 3 business days SALES TO THE UNITED STATES ONLY WE WILL CANCEL ALL SALES TO FORWARDING COMPANIES THAT SHIP OUTSIDE THE USA About Our Parts We are under NDAs (Non-Disclosure Agreements) with different manufacturers to buy their overstock parts. All of the parts we receive are factory original parts. Some of our parts have the manufacturers stamps and logos as you've seen. For example we might have parts marked Colt, Springfield, Smith & Wesson, Remington, Lone Wolf, FN, Sig Sauer, CZ, Springfield, etc. Or, we might receive the parts before the stamp is applied. Most of our parts are excess inventory that these companies overproduced because they overestimated how many guns they would sell. On some of our parts, we can ask the manufacturer to produce some extras which we then purchase (called a strategic overrun). On some of these strategic overruns, we can ask the manufacturer to slightly modify the parts to make them specialized. For example, we might have them make a barrel longer with porting, or apply a different colored finish, or custom cut a slide for a better appearance. In any case, our parts are all top notch parts that you would expect to get in a brand new gun. The nature of this business model has pluses and minuses. The pluses are you get top quality original parts for less than you would pay otherwise. The main drawback, however, is that for most of our parts we cannot just pick up the phone and order more. Obtaining most of our products is hit and miss. Some items are produced enough that we can get more relatively easily, but others depend on if there was overstock accidentally produced. So, if we have it in stock, get it while we have it, because many of our products we can only get once and might not ever have an opportunity to buy them again.
