    I just soak with CLP and call it a day. I'm not convinced that any one gun oil/lube is dramatically superior to another. If you want to try automotive engine oil, I've heard Mobil 1 is the choice of those who prefer engine oils for lubing firearms.

They covered the shipping and UPS showed it was delivered to their location on 1/25. Again, this was solely going to be a spare, so I wasn't in a rush to get the new one back. I didn't even contact them to ask about the status of my replacement; although I was getting to that point, having not heard anything from their end. I figured I'd call today on my way home from work, but my wife texted me in the late morning saying, "That thing from that place showed up." Unsurprisingly, I knew exactly what she meant So, a week turnaround wasn't bad, especially considering that I wasn't hounding them to move things along.

    Aside from the primary extractor problem, the first one also had an "issue" with the ejector roll pin; being mushroomed on one end. The replacement was perfect in that regard. I broke everything down and all looks good. The extractor is nice and snug, with good tension. One interesting difference between the two was the color of the o-ring. The first had like a deep sandy reddish color. The replacement had the traditional black ring that I'm used to seeing. So, maybe they did grab the wrong spring/insert/o-ring combo when putting the first together. Regardless, I'm pleased and grateful they were quick to make it right. As for the rest, it seems like it's well made. Good staking and chrome lining, which were also fine on the first one they sent. The staking was particularly consistent for the sample of two.

    Now, I do have a question about the initial cleaning. The BCG was described as being, "packaged dry" and having a "dusty appearance." They weren't lying, and you can make this out a little bit from the photos. Although, while true for the carrier, the bolt clearly had been lubed.

    Generally, I clean a new BCG with Gunzilla, lube it up with Slip EWL 2000, and call it a day. However, I've recently seen some comments across the web with people saying they soak new BCGs in motor oil. Anyone do this here? My searches didn't yield any specific threads on that topic. So if you do, what type of oil do you use? What's the benefit over just wiping the whole thing down with CLP and Lube? Do you soak it fully assembled or broken down? Are there any downsides to this method? Being a spare, I'm up for trying something new.

    Overall, I'm happy with the outcome. While I'm a bit puzzled how the first BCG made it out with that extractor issue, I feel the mfg went above and beyond by insisting it be replaced. I'll test it for function when the weather allows, and then toss it in the spares bin.
    I, ironically (and thankfully ), received a toolcraft BCG in the mail yesterday as one of the last pieces for my 10.5 pistol build.

    I sprayed the crap out of it with rem oil, full disassembly, cleaning with paper towels.

    The upper was kinda dry, so I Slip2k'd a good wet layer, used my fingers and evenly coated all parts of the bolt. Reassembled and performed gas ring test.

    While bolt is upright, I added 2 extra thick drops of slip2k on both sides of the bolt, fed it into the upper, and charged it until it felt smoothish. 10 rounds later and it was breaking in well. After I hit 50 yesterday, it was getting dark, but you can really tell the difference between the fresh bolt and now.

    The last BCG I prepped was in a Colt and the rifle came coated with a preservative. I found out the hard way the preservative mixed with Frog Lube turns gummy and gums up the works. I cleaned off the preservative with acetone (which worked ok with some scrubbing with a rag) then lubed.

    You can dunk the BCG or wipe the lube on with a rag, which ever you prefer. The most important part to lube is where the bolt slides in the carrier

    Thanks for the input everyone. I'm thinking I might skip trying motor oil and opt for a slightly modified version of my usual method. I use a product called Tuf Glide on the exterior of my firearms. Not only does it make them look great, but it's proven to be a pretty good protectant/lubricant. Normally, I'll spray it onto a microfiber cloth and then wipe the exterior of my slides, barrels, rails, receivers, etc. For this new BCG, I'm going to clean and lube with Gunzilla/EWL as normal, and then spray the exterior down with some Tuf Glide. Then let it sit overnight and then wipe any excess. Maybe re-lube the bearing surfaces on the exterior with some Slip if necessary.

    Not that any of this matters to anyone. But, if someone happens to have experience treating a new BCG with Tuf Glide, please feel free to chime in. Thanks!
