What are some good complete lowers? I am looking to 'build' my first ar but I dont thikn I would be able to do the trigger and ish by myself so I am looking for a complete. Spikes and BCM seem to have a good rep but is there anything else out there? going to go with a .300 blackout I think..
I guarantee you can assemble the lower by yourself. It's ridiculously easy... everything just snaps or screws together.
The upper is another story. Properly mounting and torquing the barrel involves special tools like a vice block, barrel wrench, etc. If you assemble the BCG yourself you also have to stake the gas key and headspace it in the barrel extension. More special tools required.
I'd buy a complete upper, a stripped lower, and a lower parts kit for a DIY AR. No special tools required. :cheers:
EDIT: Just realized I didn't answer your question... a lower is a lower for the most part among the entry level to mid range brands. Pick the brand you like best. I prefer to match the brands for the lower and upper receivers. I think it gives a better/tighter fit between them if they are from the same manufacturer.
