... Roller locked guns are junk. That being said...
This is just an ignorant statement.
In your opinion which your certainly entitled to. That being said, you know what opinions are like...
As it applies to GunGeek, the legend and lore of the G3 is built off of the GenX'ers who grew up reading Soldier of Fortune and dreaming about responding to an employment ad in the back of the magazine. The rifles have been in a few battles but never a war.
While the G3 was an OK battle rifle, it's not the invincible, super tank AK battle rifle that many believe it to be. Jim "Mr. HK" Schatz weighed in on the subject years ago:
"There are lots of roller-locked fans around the world and that is good. However the facts are that the blowback-operated roller-locked bolt system while good in its day (1940-1960's) is no longer state of the science. It was not selected by its designers because it was more reliable. It was selected because of unique production and assembly concerns during German war time conditions. It is in fact more sensitive to ammo variances and one of the only modern rifle systems that requires problematic chamber fluting. As mentioned HK tec reps traveled the world with MANY (80+) different G3 locking pieces to "adjust" weapon function with different ammo found around the globe."
If the rifle is maintained, it can last a LONG time. However cleaning/maintenance on it sucks and it's expensive. The fact that you don't need a 1-ton press and a welding wizard to facilitate a barrel change is a clue.
The rifle is ahead of the curve on traditional battle rifle accuracy, but it does not lend itself to easy customization outside HK parts and a small lot of decent aftermarket parts (discontinued KAC rails, B&T mounts, Spuhr). Even then ergos and controls are not something a good shooter would tolerate. HK roller locks can be made to shoot VERY well with a great deal of effort, TLC and often a TON of cash.
All this as it applies to a REAL G3/HK91. As soon as you buy a clone, all of your problems will get compounded by tenfold.
