Spikes Complete Upper

[Mike69]

Slickmag for 20 off

This is the one I used.

Just got a email from them saying thar some parts are on backorder with no ETA.

One more question, would it be better to go with a Daniel Defense LPK rather that Spikes?

From what I've read they are about the same quality (stainless parts, coated) and the Spikes are generally sold for less.
