I've got a 2006 vintage Bushmaster lower that I would like to build into a higher end platform. According to the 'chart' it appears as if most of the key, quality components pertain to the upper receiver. I plan on replacing the buffer tube and stock but leaving the rest stock (BM lower and BM lpk). I ask this because I have a LGS rollmarked Spikes lower with a PSA LPK that I prefer with another build but could possibly use instead.
By quality build, I'm talking about something like a BCM Upper. Would you feel comfortable slapping one of those on a Bushamster lower? |
| I have two BM lowers (circa 2001-2002). One has an SSA trigger with a BCM upper and the other is shared between a modified BM upper and a dedicated 22LR upper. Neither has been an issue since new. Generally, the lower is less of an issue (quality wise) than the upper. You can always replace the parts with a known quality LPK if you have doubts. |
