G3 Bolt Locking Piece

Just about every time I am assigned another G3 part to describe, it is like I am back in school all over again – ready to hit the books and learn something new. Sure there are those few times when I get a part like the G3 hammer or the G3 sear and I don’t have to stare at it for 20 minutes while scratching my head to figure out what it is and how it works. Then there are those other times; times like today, when I pick up the G3 bolt locking piece and scramble to discover its purpose along with all the intricacies that come with it.

The G3 bolt locking piece is located inside the bolt carrier on the G3 rifle. By pressing against the bolt locking rollers as the bolt carrier moves forward – forcing them into small recesses – the bolt locking piece serves to lock the bolt in place while the rifle is in battery. It also aids in releasing the bolt from battery and acts as a guide for the firing pin. It is an original factory part made in Germany by HK.

Spare parts are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly, including the bolt carrier group. If a part breaks or fails, a repair or replacement is necessary.

It is also important to consider availability. At this time, Keepshooting.com has a wealth of authentic, original factory parts from HK for the G3/HK91/PTR91. Not only are they readily available, but also they are cheap. Now is the time to take advantage.

Review by Michael
This is one part that you will experience wear on. Once it wears down, it will not lock your rollers properly. That could go really bad for you. It a good idea to replace your rollers at the same time so the fit is perfect.

Better than what I had
Review by RemMax
I just got mine in today and dropped it into my G3, the cocking piece I received was definitely not new and showed some signs of heavy use in its life but it is still a hell of a lot better than the one I had in my gun and it didn't cost me $28.00 to buy like a new one does.
In my case I don't shoot my G3 very often so I'm happy with it.
On the other hand if the G3 is the only 308 you own then this may not be the best way to go as they are from used rifle.
Overall though these are well worth the price and I am satisfied enough with mine that I'm keeping it.
I'll take it to the range sunday and I am pretty sure my G3 will function a lot better with this replacement part than the worn out part it replaced.
