Quoted:
I wish military carry handles came with an F mark too. I have a heck of a time sorting them out.
Or that Bushmaster had not refused to use "F" height FSBs or at least taller sight posts when needed - and to avoid this very simple solution, instead made their own entirely ass-backwards carry handle? Would have made it much easier... you know, to do it right the first time.
But as far as most commercial manufacturers are concerned - the .040 offset affects only about 15% of carbines only (not rifles) so chances are, most people will never zero their irons close enough, and never notice that they can't zero properly. So, rather than do it right, they simply take the risk of a couple people a year complaining - tell them to buy their taller front sight post, and let the majority of the knowingly miss-assembled carbines remain unnoticed.
The "commercial spec" detachable carry handle is one of the worst examples of the failure and refusal of a lot of commercial companies to build proper rifles and passing off the possibility of failure to the consumer. If they're willing to take a risk of 15% of rifles being unable to be sighted in properly and send them out the door, what else are they willing to push to the consumer when they know it's substandard?
