A few months ago I bought the new Beretta ARX160 from Suffolk Rifle Company. These are like the other Umarex rifles, made by them but marketed by the respective companies. Unlike the earlier rifles it is a whole new bolt design.

Firstly it's mostly polymer, like the original ARX160, however, it doesn't feel cheap, the collapse-able, folding stock locks firm with no wobble whatsoever. It's is pretty ambidextrous, safety lever on both sides, the charging handle can be swapped over, sadly unlike the original, ejection is for right handers.
The iron (plastic sights) are ok, they're basic, nothing special, but to be honest I never had any intention on using it and fitted a RS55 instead.

Stripping is very easy, just fold the stock, rotate the safety beyond the S position, and push down on the back of the bolt stop, the lower then swings away, pull the charging handle out and then remove the bolt. It's simpler and faster than it sounds.

Reliability wise I have had no issues, though to be fair I've yet to put over 1000 rounds through it. However, it has had in the region of 600 rounds of minimag through it. With that it has had 1 stoppage, the was hammer riding the bolt into battery, I was doing some seriously quick shooting as a function test. I have done some more rapid shooting since, this hasn't occurred again.
