I recently purchased a Windham Weaponry AR-15 and absolutely love it and for the price, cant be beat wit the quality. I do have a few questions I hope someone could assist in. I want to spruce it up to go along wit the S&W 15-22 I have so I can get a similar experience between shooting the 2 gear wise. It currently has the standard, solid hand guard and a fixed Iron front sight and a removeable carry handle. I am wanting to add a picatanny rail (think its about a 7 inch thats needed) and add a scope with flip up sights. The question is, since I have the fixed front sight, is it possible to take it off myself or so I have to circumvent my thought process and upgrade differently without spending an arm and a leg to do so? Any insight, help, and assistance is greatly appreciated!
