Now that's cool, I was going to ask what that was from, it looked familiar but I couldn't tell what it was from.the triger housing and grip i found on ebay for $16 bucks its for a paintball gun solid piece of aluminum
Other then the red I like the design, simple but looks very durable.
Your main weakest link is the trigger linkage, as long as you got that figured out it should hold up well even in harsh conditions.

ado,, I'm not sure if you have a rod or plate type trigger linkage? The one I had , had a rod. What I did was to use a larger diameter rod(stainless tig rod),sling swivel posts to act as guides for the rod, and that tightened up the trigger assy. really well. I also used aluminum model airplane clevis on both ends to use as adjusters further tightening things up inside. Just hold the holes for the clevis cross pins to a real tight tolerance to avoid slop there and don't forget the clevis lock nuts.
That seemed to solve,, all ,,,the problems I've found with the sloppy bull pup triggers. Hope that helps out if you need to do more work on yours.
A bullpup in .223 cal is the way to procede in today's market and crazed, uncertain world.
