MCARBO Ruger PC Carbine Bolt Head Pins & Extractor Pin Kit

Quick delivery! Very well made product. Stronger than stock parts. Thanks guys!

I did some research before purcahasing these and there were definitely mixed reviews. I was a little apprehensive, but I did purchase and install into both my PC carbines, It's true, They did fit very tight the first time installed, but after 200+ rounds through both carbines, they are withstanding the abuse quite well, with no sign of wear as of yet. The factory pins after 500+ rounds were definitely showing some wear. For the price point, and quality of material, Its a worthwhile upgrade in my opinion.

These are so much better than the stock pins. They fit a lot tighter and don't fall out when removing or replacing the bolt assembly.

Despite Ruger forums and previous reviews I went ahead and bought these anyways. After installing these MCARBO bolt head pins, the fit was FAR too tight for my liking. Bolt head literally had zero wiggle room after installed, consequently, the extractor pin was the only pin I felt comfortable using. I did end up contacted a Gun Smith at the actual MCARBO HQ in the U.S.A, the gentleman I talked with said that after installing the new pins, there should in fact be movement in the bolt head. After about an hour of trying to get the new bolt heads out, I put the Ruger OEM ones back in and only ended up using the extractor pin. After reading reviews and forums it seems some people are having the same problem and some aren't. At the end of the day, I didn't feel comfortable with how tight they were when installed as well as the MCARBO Gun Smith stating that there should be movement with the bolt head when mine had zero.

Unfortunately only the extractor pin is usable. Ruger has changed the measurements of the bold-head pins in someway on newer versions and the bolt-head pins included in the package no longer fit. They are VERY tight, and once in, provide no slack movement in the bolt-head and are almost impossible to take out. This has been confirmed in by M-Carbo in their forums. So far no alternative available.

Easy install and will last longer than the OEM pins.
