Question on the Ultra Lite Grendel. On the Bushmaster upper,
1] was it the older style with the fwd assist and ejection port door, or the newer one that lacks both of those? http://www.bushmaster.com/products.asp?cat=601
2] what barrel and barrel nut did you use? I am looking into using the Bushmaster Carbon 15 upper for a different build and saw this FAQ http://www.bushmaster.com/faqs/afmviewfa...ght=carbon, which seems to denote you have to use certain barrels and certain barrel nuts. The Barrel nuts they used, apparently don't allow for the install of most free-float handgaurds.
