As far as I know Ceiner is the only game in town when it comes to the sear trip and anti-bounce weight. However, CMMG is nearing production on their updated design. You can look in their industry forum for the details.

Only Ciener still has the trip and weight in production at the moment.

Several of the conversions are compatible with the Ciener weight and trip, though, including the CMMG and CMMG Evolution systems, and Spike's ST22 was, and may still be compatible.

The CMMG Evolution forward assist and bolt hold-open features are not compatible with the Ciener weight and trip, though - those features will have to wait for the CMMG weight and trip to be functional on a full auto 22 system.

I've got 2 sets of CMMG's FA Parts that were sent for Ron Williams and I to test. They should be available soon. Ours work perfect with an M16 Lower.....
Even used the Trip without a bounce weight by adding a longer lakeside recoil spring and 1250 FPS Ammo...
The Upper is a build using a Clint Beyer, 1:9" Twist, 22 Barrel. Suppression done by Ron Williams. Very Accurate Too.

First Set



Second Set

waiting for CMMG then sounds like the way to go.

am wondering if one has a CMMG semi-only (at this time) upper, will it be able to be modified later with a different bolt/trip assy to allow it to function FA in a registered FA lower?

if so, i'll go ahead and get an upper and await the conversion unit and/or parts needed for later....

The sear trip and anti-bounce weight are placed on the normal CMMG .22 bolt. There is not a separate bolt for full auto and no modifications are needed to the bolt. The added parts are held in place by the upper receiver when the bolt is installed. I’ll see if I can dig up a few pictures later.
