Not trying to hi jack the thread OP but here is a range report from Reddit user Quesnelmultigun
Going from tip to butt
Potentially a new muzzle device, though if not we assume the A2 Birdcage will be used
15' handguard as standard
Improved gas system, only the piston and a Banjo bolt are now used which is much much easier to take apart and put back in
Non-reciprocating charging handle that has a detente to remain in place
90' angle magwell- left side charging only
Improved and more ergonomic BCG hold/release
Improved standard AR safety- Improved ability to take in drop in AR trigger packs
Standard Gen 2 trigger will be better than Gen 1
Beavertail or non-beavertail AR grips can be used, A2 will come as standard
Significant weight savings and improved handling through curved receiver
2x captured take down pins for a tightly locked together upper and lower
Interestingly when we tried to force an over-insertion of a magazine we found that the bolt hold open leaver is under such tension that once the magazine that was forcibly over inserted (by holding down the mag release button during insertion) was let go of it pops down into a regular place. We could not replicate this with e Gen 1, is this a one off or a new vs old spring we don't know.
Currently the rifle is priced at $1400 and due for delivery to shops in March/April. Right now if we had to choose between the most recent MCR ($1600) and the Gen 2 ($1400) we'd point to the Gen 2 as being better value for money and also likely to be more available based on previous production numbers.
What will shape the success of this rifle is likely to be the cocking handle and piston, if both play nicely then it's a winner.
We've put less than a 1000 rounds through it, we're not posting an end verdict till several thousand have passed through.
So far though on appearances it's a better rifle than the MCR.
Unfortunately KD requested we return it after we had put only 1250 - 1500 rounds through it
No failures or malfunctions at all. Honestly it shouldn't be any different from the Gen 1 in that regard, not that they've gotten rid of the vast majority of issues with the Gen 1 it should be a reliable good quality for money rifle. But we just didn't have the time we wanted with it
Accuracy is the same as the Gen 1. With Barnaul 55gr we got 2 3/4 - 3.25 moa groups.
With better ammo I anticipate 1 - 2.5moa depending on ammo used and number of rounds in the group.
We don't feel we've put enough rounds through to claim it 100% has no issues.
We have not had any issues so far though.
