hello all..
i have a complete flat top 20" upper and a complete A2 upper with a 16" barrel. i would like to swap the barrels so i have a 16" lightweight flat top upper and an 20" A2 upper. I did find the post a few weeks back and it does look simple, im getting the tool and the receiver blocks tomorrow. my question is what should i do with the bolt and carrier? should i keep JUST the bolts together with their respective barrels, and keep the carriers with the mated uppers, essentialy swapping the bolts in the carriers, or should i just change the whole works-the whole bolt/carrier group to match the barrel and not worry about the upper at all? I wouldnt even bother, but i want an eotech and i was never crazy about the removable carry handle/sight system either. I have a tendancy to over-complicate things and stress over stupid things alot....this doesnt seem to be an exception either :-( from what i have seen in ohter places, it isnt all that big a deal anyway. the only other thing i found was that if you do swap the bolts with the barrels, the locking lugs on the bolt and barrel tend to wear out faster. i guess it is because the bolts lugs become lapped to the barrels lugs after a few hundred rounds and if you swap them, they wear faster. even if that is so, what are we talking....wearing out at like 8000 rounds instead of 10,000 rounds...i think i can live with that.
what kind of results have you guys(girls) had?
thanks
