Please limit your email to sales/product questions. We are a sales company & are not qualified to answer gun smithing or other technical questions on design or modifications. These types of answers can be found at ar15.com or at many other internet sources.
Please note that we make every effort to respond in a timely manner, but because of the high volume of email we receive it may take a day or two.
If you do not receive a response, it is quite possible that that your email provider or spam blocker prevented it from going through. Or, it could be that we receive a lot of emails and we just missed one. In that case we are sorry, please try again, we are human & we do screw up at times. Thank you for understanding
