Sorry for the late post, but.... I've been super busy tearing up the fields with my brand spanking new midnight EGO LV1
, by the way, they are sooooooo SICK!!! Now back to the subject, the Etha Tech T MRT bolt I received from my local store was a first gen run, and yes I had issues the same issues as you have all read in the many posts (bolt guide wear, bolt spring wear ect...). However, after identifying the problems (after about 1.5 case) I contacted Tech T immediately. They are AWESOME, long story short, Tim at Tech T sorted me out ASAP, bolt and bolt guide re-honed free of charge and sent back to me in about a week. The bolt in post-warranty state is awesome (although the cosmetics side of things were much less than stellar). Smoother shot, better efficiency, and slightly quieter. You do however have to (ever so slightly) lube your bolt and bolt guide, I would recommend the Tech T gun drops as it doesn't cause bolt stick. I know PE recommends no lube, but with the faster and lighter cycling rate I think its necessary. So there you have it, is the bolt without bugs, no. Will Tech T sort you out if there are any issues, absolutely. Is the bolt a worthwhile upgrade, In my humble opinion yes (however I think ensuring you get a newer run bolt with the new honing process is the better option). I hope this helps all you Etha owners out there on the fence about purchasing the Tech T bolt.
