Well I got this piston kit at a funshow today from a dealer friend of mine, its from Brownells but looks to be a year old or so. I dont know if installed it right so I thought I would post pic to see.

God bless,

The system you have is a TNW. I've been running the same system for a while now. It has functioned flawlessly for me, mileage will vary. As far as I know Brownells doesn't carry the system, but support is available from TNW firearms, should you need shims, or spacers. From the pictures it appears you have it installed correctly, but I notice you don't have a spacer between the gas piston and the op-rod. I highly recommend going to the manufacturers sight and getting the install manual.

I bought it from a friends booth at the gunshow the box is form brownells shipped two years ago, so they might have carried them. Thanks that helped out alot.  I hope it runs well, I like DI but i thought it would be appraoate  for my 7.62x39 built :)

It was a no go at the range wouldn't cycle, and i have no idea why since Im new to pistons.

Did the system not function at all, or did it short cycle? Short cycling is an indication that the gap between the piston and the op-rod needs to be adjusted. The op-rod should just be touching the bolt carrier, I for get what the tolerance is but it is listed on the install manual.

I talked guys at TNW and tok apart my FSB and every thing, to measure the hole with is .093, then we re assemble the whole front system, I'll go to the range after class this morning to see if it works, if it doesn't function I'll record video of it.

Based on that video it appears you got it working.
