Today, I received my bolt and replacement bipod leg back from Rick Smith at SMG. I figured that, while I was sending the bipod leg back for replacement, I might as well send the bolt in for resizing too because Rick says that will clear up the lockup issue I have been experiencing with a hot rifle since it was new. I sent the parts out to him via registered mail and he must have begun work on them as soon as they arrived because he contacted me just a couple days (at most) after receiving them to tell me that they were ready to be shipped back. They arrived via FedEx packed just literally exactly as I had shipped them to him. He used the same box and even the same packing material. This was perfectly fine by me as I tend to over-pack things for protection. When I unwrapped the parts, I was pretty amazed at what I saw. I expected the bipod leg to be new and it was so no surprise there. What amazed me was the bolt. It's 100% guaranteed my bolt but it looked absolutely new. I had cleaned it off with carb cleaner prior to sending it in to Rick so that he wouldn't get a funky bolt to work on but the wear marks were a bright silver and contrasted with the overall dull grey finish on the part. I don't know what Rick did but, while the wear marks can still be seen upon close inspection, the finish is back as it was when new. Perhaps he bead blasted it? I don't know but the work is VERY professional As an example, here's what the cam slot looked like when I sent it in:
You can clearly see the bright spot where the cam on the carrier rubs.
Now, here is what that area looks like now:
Schweet! To be clear, it doesn't appear that any metal was removed. No polishing or work of any kind appears to have been done. It's just that, whatever SMG did, the original look of the finish was restored. Of course, one range trip will put it back to how it was; I just want to impart how thorough it appears Rick is. This is Excellent attention to detail and that equates to Excellent customer service.
Here's the bolt overall:
Rick also replaced the extractor spring. He said that the one on it seemed a little weak.
A few close-ups:
This brings me to what was actually done to the bolt. According to Ricks' email, he "updated" it. What this means, I think, is that he ground the bolt down in some areas to give just a bit more clearance between it and the trunnion at the front while also reducing the rear collar a hair where it rides in the receiver. I hate to use the words "ground the bolt". That sounds rough and like a rig job. Rather, he appears to have reshaped it only where necessary paying VERY close attention not to touch the locking lugs. He also blended in the work so as to make it almost invisible. Only under close scrutiny can you even tell that any work was done.
For example, in the picture below, can you tell where the bolt was resized?
I myself am not 100% sure but I think I can see it. To the left of the picture and stopping approximately where the stitching on the zeltbahn intersects the bolt, you can see fine annular rings where the part was turned in a lathe. To the right of the stitching, those rings disappear. That is where the resizing was done......I think. The work is so finely done that I cannot be 100% sure. Below are four pictures showing all four sides of the bolt. I have used a China marker to show the areas where it appears Rick did his thing:
At least, that's my best guess. So thank you Rick Smith for standing behind your product! This kind of customer service and this level of Quality speaks volumes about your Integrity with a capital "I". This weekend, I plan on taking this thing back out to the range with another 100 rounds. Hopefully, the lock up problem is now gone. Of course, I'll post my findings.
In the next post, I'll show you guys the new bipod leg.
