6mmproshop Staccato P. Army Armament OEM.

This was sold here as a ‘tuned’ build but it had a few issues that I’ve spent the past couple of months fixing. Selling because I bought the T8 steel version at the same time and it took me a while to get that FCG to feel as good as this one.

The issues it used to have:

Mag fill valve and knocker valve both leaking. Tried replacing the o rings with those from a working mag from the T8, original buyer offered to fix but then ghosted. Turns out they were both busted internally. Both valves replaced with AMG replacement kit available on patrolbase.

Unable to engage slide lock when the slide release lever is pushed inward, and slide release not disengaging when racking without magazine. Fitment issue, printed rimmed washer to prevent excessive inward movement and filed contact surface. Also greased the contact surface between the detent plunger and the slide release lever, as well as removed the short stroke kit because it had no effect on the slide lock mechanism because it was just a spacer rather than a locking point change. Happy to include the short stroke washer but it’s very much not what it claims to be, it just chokes the recoil length rather than the locking length and provides no benefit to slide lock.

Recoil spring binding at end of travel. No impediment to function but it sounds gross. Replaced with Edge 110% spring but will also include original. Would recommend the AMG winter spring for the WE hi capa, it feels great in my T8.

Gritty and blobby feel to the slide action, and depositing paint gunk into the FCG with use: After removing what looks like cat hair from the action, found that it had been oiled rather than greased. Regreased.

The claim from the first owner was that the contact surfaces had been polished and this is true for some surfaces, but the 2 disconnector tracks were untouched and so it was wearing paint off of the slide, mixing it with the oil, and then dropping it into the FCG. Polished disconnector tracks, disassembled lower completely, cleaned and regreased FCG.

Gun was firing upon inserting a magazine or upon releasing the slide. Original buyer tried to convince me that this was because I had tightened the screw in the trigger and I left him to it (for reference, the trigger screw prevents overtravel of the trigger past the sear engagement point by acting against the magazine release, it does not provide a function prior to this point). Modified leaf spring center leg to fix the sear to hammer engagement, as it had been previously modified presumably in the name of lightness. The sear and hammer contact surface has been polished by previous owner and feels good.

Magazine release was gritty, disassembled and regreased.

Previous owner also claims that a cowcow enhanced cylinder head has been installed, but it performs the same as the T8.

Hopefully this all explains that, while it had a rough start to life, it has now been properly sorted out and looked after. Package includes original box, Holy Warrior RMR and Sotac X300UH-B

It’s also worth noting that, while I’m able to provide a battery for the RMR, I do not have any CR123’s to spare for the light.
