Photo of F5 Drum on Scorpion EVO PCC.

I'll post some photos tomorrow. My experience is flawless operation thus far with F5 (2 Scorpion Drums), and problematic, unreliable operation with X-Products (Colt Pattern). The drums are compact and make it easy to manipulate the rifle. Super long magazines are not conducive to prone shooting. Best regards, Jim

Go with F5. Works right out of the box. Outstanding product and customer service. Best regards, Jim Taylor

I have the same problem. I have smoothed the transition area between the mag body and extension and made it a little better. Still, it is not ready for a match. Best regards, Jim

Weber Tactical www.webertactical.com Very high quality. Best regards, Jim

Yes. I am running the Kynshot hydraulic buffer and JP AR-10 spring. Shooting 147g Blue Bullets with 3.2 gains of HP-38 powder.Just over140 Power Factor put of 16 inch barrel. There is noticable springiness with a regular carbine spring that disappears with the .308 rifle spring. Recoil is very manageable with dot never leaving the glass (C-more on one PCC, Vortex Sparc on the other). Note that I run an EFFIN A compensators as well. All in all, very smooth shooting in both of my PCCs. Best regards, Jim
