Re: Which one is better M&P 15 Tactical or Spikes?
Look into the LMT rifles first, or rather their built uppers and built lowers. Or maybe even a Colt. For a similar or slightly higher price, you can get a finer weapon I think. My LMT is about 1-2MOA with good ammo and an EoTech.
I built mine to be a SOPMOD copy, so I have a little more into it, but the base rifle cost about $1000 to assemble, and by assemble, I mean throw in the carrier group and pop in both pins. How much you spend from there on rails to whatever is up to you.
If you buy the LMT Patrol carbine, it will be the same basic rifle but with a rear sight and for $1484. Better to assemble it yourself.
