I don’t think there are 1000 BCL102 rifles in public hands yet. A smaller production run of 100-200 would probably be better. Ask $350-400 to make it worth his while.
Use 7075, get them anodized, don’t machine the port door pocket too large, drop the goofy round interface for the BCL handguard, and make sure aftermarket charging handles fit with out modifications. Maybe offer DPMS 1-7/16 - 16tpi barrel nut threads, instead of the Armalite 1-7/16 - 18tpi barrel nut threads, so we have more handguard options available to us. Or offer both barrel nut threads options. Maybe even offer a forward assist for those of us who want one.
