Let me answer this...and I can be corrected by anyone who feels I am wrong.
Mac Dev MAKES aftermarket parts for guns...that was their beginning, (Oh and killer air systems).
Gladiators and the LPRs rule, they are aftermarket parts to upgrade most guns. No need to change those.
The Barrel is a decent aftermarket barrel, add a few more backs for bore sizes, and yer done. You don't NEED to change it, tho some people will for personal preference.
The board is comparable to a WAS board, leave it alone.
The bolt is fine...leave it.
The trigger, now THIS I would change, because I don't like flat triggers. Again, personal preference.
GRIPS...I put new DYE Sticky 3 grips on mine, and I love them.
Neither the trigger or the grips really affect the performance though.
I would rank the gun an 8 out of 10 for how well they got the optimum performance out of the Cyborg. I can't imagine what they'll do to improve it, (aside from asthetics for those who find it too boring) but nothing is perfect. The Cyborg has everything, efficiency, speed, lightness, size, ease of maintenance, and value for your dollar.
Just my opinion.
