Better lower? MP15 or Spikes?

trying to decide on what lower i wanna put on my carbine, i have a spikes zombie lower with a bushmaster internal parts kit and a mp15 complete lower. what one is better quality? for some odd reason the mp15 lower feels a little “smoother” in the actions. what do you guys think?

For the most part a Lower is a Lower is a Lower…with the bug differences being the internal parts used. Flip a coin and use whichever wins the toss.

It doesn’t matter too much. If the M&P feels smoother, I’d go with it. Are you running carbine buffers in both?

I’m pretty sure that the parts in a S&W lower are higher quality than a Bushy LPK. As long as the receiver is dimensionally correct, and both Spikes and S&W generally are, the LPK determines how well a lower works. I would take S&W over Bushy or DPMS any day.

Both lowers are gtg. I personally don’t care for the zombie stuff at all though. I think the general feel on this forum as far as the quality of lpk’s is s&w>bushmaster.

For what matters, you’re comparing a Bushmaster to a S&W.
S&W all the way…period. With a complete S&W lower, you’d probably have some warranty…just in case.

But maybe it’s just me…

Fuck Bushmaster, that is all.

Put the M&P internals in the Spikes lower and call it good.

If both lowers are dimensionally sound, no real impact as to roll-mark (brand).

The Smith will have the better internals. Advantage, S&W.

If you have problems with the Smith, and have the opportunity comes to call them up for help, you’ll get help. With Spikes, it’s entirely edpendent upon a Magic 8 Ball and the hormonal balance of whomever answers the blower as to whether or not you’ll get help, ambivalence, or encouraged to engage in a physiologically improbable solo sex act. Overwhelming advantage, S&W.

THAT’S the reason to avoid Spikes, if one chooses to do so. It’s rarely ever their STUFF, it’s the fact that their willingness to support it skitters around like a drop of water on a hot frying pan. What they sell is usually in the ‘okay’ range of quality, but one shouldn’t have to spin the Wheel of Destiny if it comes time for them to competently and professionally support their product.
