Rekraps

Finished Mac Daddy project. Crown MB series re-do.

CIA can at the UK Royal Armory.

Very nice. TomK is 100% correct in that having all the spare parts finished at the same time gives uniformity in the finish. Like you however, I choose the CIA integral suppressor route. Took forever to find a craftsman to make it, but Joe Jones with Shaw Armament did an outstanding job. I have one of one! Who knows if he'd make another. It looks exactly like the one in the UK museum and shoot great! I have two "K's", both Andrewski units and shoot the Port Said with integral all the time, leaving the Mac Daddy unit for.... well I don't really know what for. All the MB and L series guns are M45's which is quite nice as you can remove the magazine well. My Mac Daddy unit is a complete Crown job (CJ if you will!) and even the front sight post has a tiny crown stamp. The Port Said unit is 100% Egyptian.

You sir, will get a very nice end-product. Hopefully you asked for the "Mac Daddy" redo. Mac Daddy is this: "John... make the gun like you would like it." The older Wilson guns (both L & MB) series were low cost units when they were first manufactured, so the work that went into them was not as extensive (price/value). Now that the costs are way up, John is remanufacturing a select number of the guns (all booked up for 2026 already!) to include the infamous MB series (which he and his dad did not originally manufacture). It'll cost you, but the final product is first class. The entire gun is taken apart, to include removing the upper receiver from the lower, re-aligned, re-welded, all parts blued or painted or parkerized, locking tab receiver cap installed if you want, then re-riveted, and returned. OEM guns are not as nice! Make sure you have him blue some matching crown magazines and coffin mags (if you have them). I even had him rebuild the brass catcher assembly to match.

TSMGguy speaks wisely. Do a bit of research before you sell the parts. Original parts are scarce.. Barrel assembly and lower R look nice.

Good advice all.

Is that a vintage steel zipper or the new plastic one?

For once I am certain. The most valuable are M16A2 US Property marked gun with. S/S/A functions. It matters not what people put in the gun after they buy it, it's the OEM configuration. The 8000000 serial number make it a "common" gun (if there is such a thing) for A2's.

Like three levels above my pay grade! Agree totally on the three piece design considerations, but the rest, while interesting to me, does not impact how my gun operates. It shoots! My hunch is that a shorter recoil spring will exacerbate any potential damage to the spring guide by allowing the bolt travel to increase AND allowing the bolt to potentially impact the rear surface of the guide. For my gun, I installed a 1/16 inch rubber washer around the recoil spring base (fits nicely, HD!). Frankly, I don't know if it does anything, but considering that most SMG's have buffers, I figured it could not hurt.

Any wood stocks w/recoil pads?

Great point. The Lanchester bolts can be used in the MP18, and accommodate the MP18 OEM mags, but not the other way around. The KMP18 bolt "ears" on either side of the ejector guide are too narrow (although they look very close) to allow for the Lanchester mags (STEN) to fit. Whereas, the MP18 magazine feed lips are narrower and fit the narrower guides on the MP18 bolt.

Both of mine show some impact damage, although I don't know if it is from the bolt or maybe someone dropped them when cleaning. In either case, it's clearly a weak point of the gun, so I had solid billet spring guides made. The OEM guides are made of several pieces that seem overly complicated considering the idea of the gun was to simplify the design.

It's hard to believe that seller is posting the gun with the description he has. Buyer beware!

THANK YOU for the clarification! I thought Spring Creep was my neighbor peeking in my windows with the nice weather!

You guys are so funny. It's a MP Lanchester II. Even I know that.
