I'd like to verify the range of front sight widths used in HRA production. I have 2 HRA rifles which were received with the fol front sight widths;.719 (s/n5653717) and .725 (s/n 4794032). Also have spares measuring .736,.737, and .738. My understanding is that all of these are in excess of SA manufactured sight width and narrower than those made by WRA and IHC. Any definitive info on just what minimum/maximum width front sights were produced by HRA?
