    Okay guys here are the prototype extractors. They are being sent off for coating and then we will start testing them out. These are for the 223/556 caliber. uploadfromtaptalk1405473474622.jpg

    I heard tonight that they could be here as early as tomorrow. That means Friday will be a fun day.

    Okay so the guys at the machine shop did a great job once again. I have two of the untreated extractors here and the other coated versions any day now. So with that being said Friday is going to be fun. uploadfromtaptalk1405552293763.jpg

    Titanium nitrited parts came in late Tuesday afternoon. They look fantastic and fit into the MVP bolt quite nicely. All that's left to do now is to take them out to the range and run some steel cased ammo through the rifle to see how it handles the abuse. Rob and I should be able to report back sometime after this weekend with the results. Thank you all for your interest. We haven't given up by any stretch of the imagination. It just takes SOOOOOO long to get things into production. Here are a few shots of the prototype parts. I've added a few refinements to the extractor that I hope users will find helpful. One of them is the addition of a small thru hole in the cup of the extractor that will allow you to insert a small pin through the hole and easily depress the ball bearing and the spring during diss-assembly. It really works well.

    Looking forward to the release of this part as well!

    Looks great, are you guys upgrading the ball bearings or just reusing the stock ones? On savages they put a slightly larger ball (.140 I think) to help with extraction/ejection.

    Please include a new ball bearing and spring with the enhanced extractor! They're too easy to lose.

    Is there a ETA on the extractor? How would it be possible to get one?

    As far as packaging goes, Rob and I were thinking of selling each extractor with a new bearing and spring. Since I'm the crazy one, I had even suggested that we titanium nitrite the ball bearing so it also has that beautiful gold color. I know...nobody would ever see it, but you'd know you had the baddest extractor assembly on Earth! We're doing a lot of concurrent testing on both the extractor and the new magazine release. I'm looking now into sourcing a new heavier duty spring with a slightly stiffer spring tension to prevent the shooter from accidentally releasing the magazine should he lightly bump that awesome new magazine release. Since Rob and I both do the 60+ hour-a-week thing on top of this really cool gun part business, I cannot give any firm ETA's on when everything will be ready for release. I can tell you that it's all Rob and I are thinking about, so getting these new parts to you all as quickly as possible is our highest priority. We will definitely keep everyone here in the loop. Thanks again for all of your feedback! Happy shooting.

    Wood Chucker, you couldn't have been more right! Rob and I were playing with the new extractors over the weekend, and I was attempting to put one of our new titanium nitrited parts into the bolt assembly when I launched that baby into orbit. We quickly discovered another awesome side benefit of that beautiful gold color is that it shows up easily on the ground. Who knew? We won't be able to nitrite the spring, as flexible parts are not the best application for this surface treatment, but the ball bearing is definitely doable. We haven't had a chance to get out to the range yet and put the extractor to the test, but we did discover one additional design change we probably want to make before going to testing. I'll be all over those modifications this week, and hope to have some new parts coming back to us ASAP for testing. As always, you guys will all be the first to know what progress is being made. Happy shooting!

    Oh my god. This is everything I have been dreaming for for almost a year. Mossberg never replied or answered to me and I haven't shot my gun since I got it and the extractor broke. Can I please PLEASE be one of the first ones on the list. My gun is waiting to be shot!!!!!!!!!! I seriously CANNOT WAIT FOR THESE!!!!!!

    Wouldn't hurt my feelings at all if the disassembley hole in the extractor was deleted to cut cost and save time.

    I'd manage to pack it full of mud/snow/ice anyway.

    Hello Wood Chucker,
    I just may omit the hole, as you mentioned, and go with the stock design. The one thing I quickly discovered in the prototype was that the hole allowed the bearing to sit a little lower than normal as the bearing nestled into the new tangent point provided by the thru hole. You just never know what you're going to discover until you take the plunge yourself. The guys at the machine shop threw that little ditty in at the last minute when they suggested that it might be a cool feature. I'm glad I only had them do it in a few parts because Rob and I were able to put a caliper across the two different assemblies and actually measure the height difference. I was amazed at the difference, but I should have expected it knowing full well what surfaces were affected by the design change. Live and learn. While the extractor is going back to the machine shop for another small run of parts with the updated drawings, the magazine release prototype turned out to be a raging success out at the local gun range! I have made the latest revisions to that part, and it's back to the machine shop for an actual production run. I'm waiting to hear where I am in the queue and will report back as soon as I hear something. Things are definitely moving along. Rob said the magazine release performed flawlessly, and that everyone at the range wanted to fondle it and give their feedback. The end result was that everyone loved it and wished that their own rifles had magazine releases that looked and felt as good as our design. If that doesn't make an industrial designer feel good, I don't know what else does!
