: kevin g  
I have done tons of research on barreled uppers through many companies and i am beyond satisfied that i chose mas defense!The reason i liked you guys was because everything was very easy to find andput together.The barrelled upper that i picked was the 16" 5.56 / .223 BARRELED UPPER - YANKEE HILL 12.58" DIAMOND and it is exactly what i was looking for! You guys did great it was assembled perfectly I ordered the upper on a frid and i got it in the mail exactly three ds later! I am more then happy with what i got and the price that i paid. I will for sure use you guys again on the next build!Thanks,Kevin Gaudet
