Beretta Xtrema Forend Cap With Swivel and Swivel Stud is made for the Xtrema 2. The cap will also work on the Xtrema and A400.
We all hated the silly sling set up Beretta has had for years. The factory QD swivel rusts any starts falling out. Convert your old style system to something useful! Now you will be able to use any sling on the market with swivels.
The factory stock insert on your Xtrema 2 will screw out with a metric allen wrench. Then simply screw the new insert in.
