I installed my RTB ENT Trigger today. Very nice. I replaced a PSA Enhanced FCG with it. It has a very small amount of creep - less than the PSA. It's smooth as glass, no grittiness whatsoever. In comparison, the PSA is a little gritty. On my trigger pull gauge the RTB trigger breaks right a 4 1/2 lbs. The PSA breaks at 5 1/4 lbs. The trigger looks like a quality piece and there were no issues with installation.
The only bad news was a glitch in the delivery. I placed my order online on Sunday evening and I expected it to process on Monday and my credit card was charged on Monday. I received tracking info Tuesday night that indicated I should expect delivery via USPS Thursday. On Thursday I checked the tracking again, this time I looked at the history. I saw the package hadn't reached the post office for shipment from RTB until Tuesday afternoon around 4:30pm. The delivery date was changed to Friday. On Friday I took another look at tracking - I had planned to go to the range Friday afternoon. The tracking said "delayed". I got the package this morning - Monday - one week after I ordered it. Maybe I'm a little spoiled by the service I get from some online vendors. Since RTB had no problem processing my credit card Monday morning, I'm a little disappointed they waited until Tuesday afternoon to send the parts. The rest of the delay is on the USPS - they didn't come through on the 2 to 3 day Priority Mail promise.
