Brethren Armament Parts
Glad to finally see some serious competition to HKParts. Example: RCM MP5 carrier- KE Arms: $139, HKParts - $179. $40 difference.
Competition is a good thing. Glad to see it coming about.
I will say this is interesting to see this and will also write, why can't we all just get along....
