So i have about 3,500 rounds thru my bushmaster what should i be looking at to replace so far the gun has been very reliable things i think will need replacing soon (just from what i've read): extractor spring, plan to get a wolff spring gas rings ( gas ring are still good as of now) things i'm not sure about, when to replace: firing pin cam pin bolt buffer spring ejector spring anything else i should be keeping an eye on ? |

when you take apart your gun to clean it just look over all the parts and you'll be able to tell if they are ok or not. Just make sure you really look at them so you don't miss something like a small crack. The springs you really can't tell by just looking but the extractor spring you will be able to tell just from shooting, I wouldn't worry about the buffer spring for a while longer. At 3,500 rounds I wouldn't worry about replacing anything big unless you didn't take good care of it. But like you said look at the gas rings and the extractor spring. from your list: If your firing pin is rounded at the tip you might want to replace that. Ckeck the cam pin for excess wear or cracks, bolt should be perfectly fine but look for hair line cracks or excessive wear and the buffer spring should be fine |
The firing pin should have a rounded tip, but you might want to check it for erosion. I don't think you should do anything to it, other than maybe replace the extractor spring with the Wolff. Then keep on shooting! |
