Is this the exact same as the: FREEDOM RIFLE KIT - 507617? I couldn't spot any differences when reading the pages. Maybe I wasn't reading carefully enough?

What will I need to complete this kit?
Quincy P on Dec 13, 2018
BEST ANSWER: You'll need a stripped lower receiver, an optic or rear sight and a magazine.
Will this complete the build if I complete an 80% receiver of my own? I have never done an AR and very much interested in obtaining my own satisfaction with the assembly process.
Lone W on Dec 13, 2018
Is the front sight removable?
Danny on Dec 15, 2018
BEST ANSWER: Yes but since the sight is also the gas block you will have to replace it with another gas block.
Does this come with a rear sight?
Ryan H on Dec 13, 2018
BEST ANSWER: No rear sight included with this kit.
Is this available in left handed?
Jason on Dec 18, 2018
Does it come with a lower receiver ?
Roger E on Dec 15, 2018

Lower parts kit missing parts so that sucks!!! Other than that it seems like it should work just fine. Not the best quality but you can't complain at this price.

M4 clone
Completely satisfied. Parts are well made and they're built on a PSA stripped lower. Shoots accurately and functions reliably.
