Must have product. Superior reliability.
Nice looking great fit
These pins are an excellent upgrade. The service is top notch
Good product, easy to install
Great looking, easy to install. Factory pins show wear after app. 500 rounds.
Fit perfectly.
Definitely an improved fit over the stock pins. We'll have to see over time how they wear, but I'm sure they'll stand up well.
I saw posts on several sites about the deformation of the bolt pins on Ruger PC carbines, so I disassembled and inspected mine. Sure enough, they were already showing wear marks after only 50 rounds fired. Hopeful that these will solve the problem permanently. Haven't fired it since installing them, but if I see anything adverse I'll report back.
The stock pins are a real weak link in terms of wear n tear. If you plan on running the Ruger PC9 hard at all, these pins are a substantial upgrade. If your Running PCC competition This pin set is a must. These pins ensure Minimal bolt face movement and help the Mcarbo extractor work flawlessly in engaging the case rim for clean extraction.
The replacement of the Bolt Head Pins and Extractor Pin with A2 Steel pins increases the the reliability of the rifle. If your carbine is used on a regular basis the stock bolt head pins will show wear and that wear could cause failure at some point. This upgrade is definately worth doing.
These pins are a great addition to the pc carbine. They will not wear as like the factory pins. They are much harder and will last a lot longer.
Made whole bolt head tighter. Smart upgrade. With limited firing I noticed OEM parts were already showing wear
New to me Ruger PC Carbine 9mm. Watching Chris's videos before purchasing, I knew I would be upgrading to MCarbo's Mussel Brake, Flat Trigger, EE Extractor, and Shock Buffer. Having watched Chris's videos I knew how to take down this weapon and inspect these parts. I knew what I was buying and what I wanted to do. Upgrading to A2 Tool Steel Bolt Head Pins was a given since they had to be removed to install EE Extractor. But, just as the video showed these pins had noticeable wear. Having done these upgrades, I feel I now shoot a weapon that is reliable.
Outstanding service from M-Carbo, My post office lost my order, then found it, but the package was damaged, and a pin was missing from the kit. I called M-Carbo explained my situation, they sent out a replacement, I really appreciated that. The stock pin kit, did not measure up to M-Carbos Tool steel pins, easy to install, with the help of their video. Thanks M-Carbo
just change the pins easy to do it, i was changing the extractor too so same time spent
Five stars is for ease of installation. I'll probably never fire enough 9mm ammo to test the reliability of the pins.
