Hi guys this pretty much my first post. I got my shipment of a new barrel a couple of days ago and was able to put it together in about 6 hours over three nights.
Here is my list of parts:
Upper:
Not mounted yet: Vortex viper HS 4-16 x 44. Vortex scope rings coming tomorrow.
Lower:
Installation:
I am considering grinding and polishing the upper in order to mate it with the M4 feeding ramp lips. The feed ramps need polishing anyway (they came rough finished and not polished). I usually hand load to mag length and worried that if rounds hit the upper receiver it will push the bullets in. Do you guys typically do this?
Can't wait to shoot it!
Anyway, I need to go cleanup my mess now
