Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Too many ask if you can easily switch out the rear adjustable sight. It is not an easy proposition due to the notch being incorrect on the Springfield air ventura, reproduction BB carbine- it is set into a square dovetail. In contrast all real USGI carbines have their rear sights set into a triangular dovetailed notch. We do not know the measurement of this dovetail on the Springfield BB carbine. Here are two photo examples showing the difference in the dovetail. If the reproduction notch is smaller than a real sight base, the reproduction replacement part's base could be filed square to fit into the Springfield's carbine notch. An easy fix. However, if it is larger or the same size some modifications would be needed and most likely look out of place or goofy.

The USGI sight base on an original carbine's rear sight is different from the cheep Taiwan reproduction sight found on the Springfield M1 reproduction BB carbine.
Here are some base views of a flipper and late war adjustable. Both have an angular cut. Source of photos are screen shots, Close up views, from flee bay. The big question is are the mount bases both the same width? Reproductions can be purchased of both types, but each will have the angular base with the correct width for a real USGI carbine. We need someone to measure the width the square cut notch(mount base) on the reproduction Springfield carbine. On a USGI sight base the measurement is exactly 0.486 inches or approximately 1/2 inch. See red line where measurements were taken on lowest photo. On a real carbine its a pressed fit, on the BB guns its held in place with screws. I have not yet seen how it's held in place on the Air Ventura Springfield BB carbine- no good close up photos.

I have not seen an actual reproduction M1 carbine either the airsoft King Arms or the BB Springfield. Here are two screen shot views of the king Arms Paratrooper rear sight from a review video. It appears to have a flat square base set in a square notch and held on by two allen screws. No angular dovetail cut base. I also added a great close up of why it is not an easy switch to switch to a real USGI carbine stock because the stock inletting is different on the real carbines. However, both the Springfield and the King Arms stocks appears similar??? This would be good to know.

A CLOSE UP OF THE KING ARMS PARATROOPER STOCK magazine area. It appears similar to the BB version. I wonder if they are the same stocks used on both the King Arms and Springfield replicas??

This second lower photo ( Bobs) shows 2 carbines: a Springfield wood stock top and the lowest stock is an original USGI carbine wood stock.
What an inletting nightmare. The screw hole and longer trigger mechanism, I doubt if anything would actually align. Moral of the story, buy a wood stock Springfield model.

So someone at the company needs to do a review indicating if USGI parts or current reproduction parts fit the Springfield Air Ventura carbine. Does a bayonet actually fit and can slide on & off easily? Does an oiler actually fit the stock and will a sling actually fit the Springfield M 1 carbine? Will the thicker & longer air gun magazines actually fit a Carbine magazine pouch- reproduction or genuine? Then, will the sling bar on the front band hold up to actual sling use- is it real metal, zemak, or plastic?
And what if a person wants to switch out the rear sight or front band? Do real USGI parts interchange with parts utilized on the Air Venturi Springfield M1 carbine BB shooter?
I wonder how it will function? Will it have problems feeding or air leakage like the Umerax MP 40? I wonder what other military models they will make: a weathered or limited production model with accurate/correct markings? Will they produce a wood stock paratrooper version? Why do they not supply a replacement seal kit with the rifle. Why not make a limited production, more accurately marked and numbered collectors carbine in a nice box? Something like the Combat vet or Commerative WW II 1941-1945 Umerax 1911 45 auto BB pistols? They also have the John Wayne and NRA.
And finally do different manufactures in Taiwan use similar parts so stocks could be switched?
I guess if we knew these answers, no one would purchase the plastic junk model--they will wait for the better editions.

The planned production date of April has been moved into June 2019. (Estimated in-stock date 06-05-19) I think more realistic from the past preproduction items where the in-store date is moved back 2 or 3 times, it may be as late as July 2019. I wonder if the wood version will be made in limited numbers due to cost.
page 1



It appears the production date has been set back again from 6/5/19 to an arrival date of 7/10 /19. So as I initially speculated they are into July :roll:
I wonder if they found some bugs in the system. Lets hope they are taken care of prior to production. It kind of sounds like we will be lucky if its out by fall 2019. :shhh: Maybe a better, more accurate reproduction( collectors edition) is being thought about. :shock:

Moved back again to 7/22/2019. Looks like a more realistic arrival date of late fall or just prior to the Christmas rush for gifts :roll: :shifty: :think: :violin: :violin:

While about the problem plagued MP40, this does not reassure me about the warranty service on Taiwan made BB guns;
Quote is from Tommy T in the Q & A section comments:
He states:
No repair service
Umarex will not repair any gun under $500. If the gun is under warranty they will replace it, but if the warranty has expired and you have a problem you are out of luck. When I sent my gun to them to replace a trigger spring I was told that their gunsmiths don't repair guns, and they don't sell parts. WTF!!!. They suggested I throw mine away and buy a new one. So much for me buying another Umarex gun.
I guess I will wait and see what the M1 Carbines record actually is, because the air soft version has a few bugs: for example:
Did they happen to make any change to the retaining nut that holds the CO2 seal in the magazine. I have the wood Airsoft version of this and could not get Crosman CO2 cartridges to install all the way before they totally leaked out. Then I tried a narrow necked precision sealed Swiss Arms cartridge and it worked just fine. This magazine may be cartridge picky.
The MP 40 also has issues with leaking and sealing its two CO2 cartridges :doh: :doh: :doh: :doh:


A QUOTE from the Springfield manual: (90) STINKING DAYS warranty only ---- On a $300 BB gun?????? :violin: :violin: :shifty: :shifty: :think: :snooty:
I see that Pyramid Air backs rifles they sell for exchange for a 1-year limited warranty. At least that is reasonable. :dance: I guess that is why you should buy from them.
