Full Rifle Service
Get your rifle to outperform the competition with KA Tech’s full-service tuning package. We go deep inside the system to clean, inspect, and refresh every critical interface—replacing worn O-rings, re-lubricating internals, and eliminating the little issues that cause inconsistent shots and air leaks.
We dial in nozzle alignment, trigger contact alignment, and selector switch alignment, then polish the inner barrel for smoother, more consistent performance. We also inspect the hop-up setup and will replace the bucking and nub if needed to keep accuracy and grouping on point.
No stone is left unturned—this is the “touch everything” service designed for maximum consistency, reliability, and performance.
Recommended Upgrades for HPA
Parts to upgrade while we do your service. No extra labor charge.Upgrade Parts
Looking for more range, accuracy, or consistency? Ask our technicians what part is right for your rifle, or tell us what you want it to do. We don't believe in upgrading for the sake of upgrading — we upgrade when you want your rifle to do something it isn't doing yet: longer range, tighter accuracy, faster trigger response, faster full auto, and more.
