I have two Bushmasters w/det handles, 20" and 16". I can't zero elevation @ 25 or 50 mtr/yds with the front post on either gun. POI is several inches high @ either distance !. Is this common with det handles ?, my A2's will zero no problem. I can bring it down some but I have to unscrew the front post untill it's loose and wobbling in the FSB. |

Yes, you will need the taller front post. Bushmaster/TDP-compliant detachable carry handles use a 1/2 MOA rear sight base, so it sits a tad high. A F-marked FSB or taller front post is required for proper zeroing. Now, if you get a detachable carry handle and it works fine with a non-F FSB with the standard height front post, chances are it is a non-TDP compliant DCH (aka non-mil spec), like a DPMS. These tend to use the wrong rear sight bases so who knows what else is out of spec. |
