The A2 works it should as its weight in gold was handed over to the rhine dwarfs of hk to fix the wretched thing.
1st designed in 4.85mm to win the nato new ammo comp as the yanks used 5.56 never going to happen.
2nd a quick redesign didnt work so ROC stole the ar18 design off sterling and bodged it into a bullpup.
3rd Maggie sold off roc to bae who looked at the sites and decided hmm nice place for yuppie flats oh my the way workers once this gats built sling yer hooks, strangely that didnt produce a quality product not that bae gave a shit
Michel klashnikov got shown one when he visted the uk god only knows why you'd that bloke builds a legendary assualt rifle and you show him a piece of crap, his comment was "you must have very clever soldiers"
Only the indians have managed to create a worse weapon the inas all the faults of the sa80 plus a tendacy to spit hot oil into the unfortunate firers face

One excuse given is the indian rifle is ideal for making sure india doesnt start something with china or pakistan
