i ordered one of these barrels which i installed in a upper everything fit fine , has strong 5r profile. slick finish and seemed to be correct in the chamber. now the gas port looks a bit large --however a rifle uses a pretty big port and the reduction in dwell adds a tiny bit more to the ports size so i think it will be OK the second barrel is identical to the first-- now i haven't fired either of um as of yet--but they certainly looking good so far--

i have two FDEs and one black and every one of them is different the first fde was loose as a goose and the barrel pocket and the pins were sloppy . had to be swapped around several lowers to find a reasonable fit that or use one of those rubber upper slack killer things. the second fde was much tighter in the pins and just right in the barrel pocket. the black one was tight in the pins but just right in the barrel pocket. all usable but just a shade off here or there -- i do like the light weight and that they match the trybe handguards and fit those perfectly. i would say that these uppers are more for "experienced" builders that know how to make up for things being a few thou off here or there -- like "gunsmith fit" sort of deal

i've only had this optic a few days. so far so good.
the good -decent glass compared to a vortex strike eagle 1-8x and not to terribly far behind the viper pst 1-6x certainly good enough to my eye. light transmission seems good @88% . the scope is big and requires a 34mm mount , seems solidly built and the turrets seem quite positive. the illumination is very good and seems daylight bright or very nearly so. in spite of it being quite large it seems to weigh no more than an 30mm lpvo- and a good bit less than a viper/pst the eye box gets narrows as it does on any lpvo as you turn the mag up yet i find it still usable @10x i like the generous eye adjustments. it also came with snap-cappys and a throw leaver --sould have came with a mount due to its odd dia- overall quailty of the build looks pretty decent to me.

the bad --so far i can't find many faults with it other than the same problems ALL 1-10 lpvos have like the tight eye box 10x , i don't think its quite fair to compare this to the viper pst-1-6x i came close to getting the swamp-fox 1-10x which i think would be closer to this model. it was quite a bit less than the fox and i wanted to try the 34mm tubes if this thing had the same glass as the PST?? all bets are off--lol

this tac upper kit has the basic charging handle , forward assist and dust cover kit. in the last year or so i have bought several of these. they seem to be machined well enough. the barrel fits quite tight. its a good kit for the $$$ cons? err it don't have t-marks
