| I'm looking to make a USMC M16A4 clone from a Bushmaster AR. Right now, my only AR is a Bushmaster 20" A2. In order to get an M16A4 clone, would I be better off getting just a Flat-Top Upper Reciever and put it on my A2 Lower Reciver or should I just save up to buy a whole new complete rifle? I figure that buying just the Upper Reciever will be cheaper but buying a whole new rifle will make for two guns instead of just one in a SHTF situation. |
Thank you for the offer but I would rather keep my A2 Upper. It just has that sentimental value being my first AR.  Any way, my A2 Upper is 1/9" profile with flash suppressor and bayo lug. |

Here's one from Cals Sporting Armory check it out -----> by clicking here  other than the barrel twist of 1/9 vs the more authentic 1/7, (and adding a R-BUIS) this is a great A4gery |

Do the military's M4's have a 1/7 twist? After reading the ammo oracle I now know that 1/7 stabilizes heavier bullets, but isn't optimal for the lighter bullets. Bushmaster's website states all their barrels come with 1/9 twist to accomodate the large majority of ammo. |
Actually, my current 20" is an HBAR. I'm trying to get it cut down to a government profile soon. |
What makes you think it is not optimal for lighter bullets? g |
