I have an upper I have built and test fired and would like to sell as a complete unit. I will consider selling it off as peices if I get enough offers on the individuial parts. This is an all Bushmaster upper.
The parts list is as follows:
Bushmaster 14.5" 1/7 twist M4 barrel (rare 1/7 twist govrnment over run, very hard to get, marked B MP 1/7 NATO) (paid$195)
Bushmaster flat top upper reciever complete with forward assist and ejection port cover (paid $150 direct from Bushmaster)
Bushmaster M16 (legal in an AR with no other full auto parts, Bushmaster wont sell these to individuals, marked B) (paid $130)
KAC FF RAS (carbine length) (paid $305)
PRI folding front sight, used the Bushmaster gas tube (paid $178)
complete with charging handle with PRI tac latch ($19+25)
I have test fired this upper and its 100% reliable for about 200 rounds of 75 and 55 grain ammo. It fires consistant 1 MOA 5 shot groups at 100 yards with the 75 grain ammo, some .75 MOA groups. I have over $1000 invested in this upper and am willing to sell it for $700 delivered to anyone interested. I love the upper but need funds for a SBR project. This upper does not come with a flash hider so you will need to permantly install the flash hider of your choice or use on a SBR lower.
