Sounds great I would love to see it.
Brass ejection distance issue - quick fix?
After examining the gas plug, a couple solutions to the shell ejection distance came to mind. The '#2' setting hole on the plug is .102" and the '#1" hole is .080". These holes are of course too large resulting in too much gas to be forced towards the piston. To reduce the '#1' ejection distance by 50% a hole of .040" is required. There are 2 options to do this: 1) either fill in the '#1' hole with jb weld and redrill or.... and this is a better option .. 2) drill a new hole with a 3/64" drill bit at the '#0' location (currently there is no hole at this location) between the '#1' and '#2' hole. Most people would never use the '#0' setting so this would be the best option. A hole drilled at this location with 3/64" drill bit (.047") would reduce ejection slightly less than 50% but close enough. Should change ejection from 8 yards-ish to 5 yards-ish. By doing this you also still have the option of using '#1' and '#2' setting should you want to.

Which cheek rest is this? Nice looking setup, I'm considering something very similar.
I just ordered and installed mine. I live pretty locally so I received the shipment with in 24hrs from ordering. Awesome.... Easy install and was put on later that same day (last week). Great fit and finish.....I added a lower rail, a folding front grip and a cheek rest for the Eotech and 3x flip zoom.
Can't wait to take it out and try it. Far superior from the original handle and sights
Highly recommend it
Is the only purpose of the 3 selections for where your brass lands or is there more to it? Would one setting be better than another when just recreational shooting? Would one setting lessen feeding issues or dented brass cases? Sorry, I'm still really new to my new T97 and havent had it out very much yet.
Each gas regulator selection (0, 1 or 2) changes the amount of gas pressure that is allowed to 'push' against the piston which translates into how far shell casings are ejected. This is more important in a combat situation where adverse conditions and lack of cleaning may interfere with cycling or shell ejection. To ensure proper ejection in these conditions more gas pressure may be required to overcome. For recreational purposes when we shoot a few rounds, lube/clean our guns after each use, give it a hug and place it into the safe... the high ejection pressure settings aren't necessary... it just means we have to walk further to find and collect our brass and our casings get more dented/mangled.
The downside of lowering ejection pressure, and which was mentioned by a member earlier in this thread, is that more of the gas is funneled out the barrel which according to Mr. Newton (every action has an equal and opposite reaction) means more recoil.
Thanks
The cheek rest is a stackable rest with 2 levels off an H&K SL8 stock. I had it laying around and it fits the upper exactly. Perfect height for the Eotech. The only issue is attaching it. So far I have epoxied the inner to the stock and the outer is screwed to it. There isn't enough space inside the stock to bolt it through with out having the bolt slide back and hit it inside.
It definitely looks like it was made for it!!
Good enough for now.
Interesting, thanks for responding.
I decided to stipple my pistol grip and forend to improve grip... I found that without anything it was rather slippery.. when manipulating the gun in various directions I was really squeezing the grip hard so it wouldn't slip out of my hands because it is so top/rear-heavy ... the stippling made a HUGE difference in grip and improves handling immensely.. problem solved...AND it looks cool

I finished up my new charging handle today for my FTU... made it out of solid brass rod. I knurled it for grip, stepped it for a larger contact OD and hollowed it to reduce weight.
The main issue I had with the charging handle that comes with the FTU was that it was not attached to the bolt body (free floating) so when the bolt locks open after an empty mag, you have to grab the charging handle and pull all the way back to make contact with the bolt body to release and load the next round after inserting a fresh mag. Takes time and didn't make sense to me.

Just picked up a t97 yesterday. Love it so far. Just came home from the shop with a couple gen3 pmags and can't get them to fit in the mag well despite being assured these would work. Anyone have a solution to this?
Couple questions about the T97...
1. I read a lot about FTF and issues pushing bullets into cartridges... Are these mag issues or rifle issues? Is there a proven way to correct this without making any home made modifications to the rifle?
2. Are these made by the same factory as the military T95? I read an article online that they were contracted out to a company that used to build air rifles (EMEI) and aren't actually made by Norinco.

this is the biggest issue i have with this gun....i hate having to bring that handle all the way back..been looking for a way to fix this...thanks.
