No matter how many unique designs are made, nothing quite beats the design feedback from the AR platform's extensive real world use against the American public.
Given production stopped in 1994 the receivers are at a minimum, 30 years old at this point. The MoD may want a domestic supplier, but BAE tore those facilities down decades ago after privatization. There’s no competition - if you issue optics and want the best for your ‘pocket army’, it’s a 416 variant or FN SCAR.
