Hi all! I registered Today, so I am new here. i want to ask you some questions.. Do you think Thompson M1A1 is a good weapon. I bought it one month ago and i think it is a powerfull airsoft gun, but you know best.... . I am just asking because i am interested in World War 2 as in modern guns... tactics and everything abaout that. Well thanks for attention, Greats, kobry

you don't have to open the gearbox to my knowledge. Don't worry about just follow directions and be carefull. As for the M1A1 it is overused but is a good starter weapon for WWII Airsoft.

I would not do the blowback modification. It is bad for the gearbox and will eventually kill it.

Extra stress on the whole meachanism. Any time you upgrade or alter the gear baox in any way you are reducing it's level of reliablity and durability. I have to believe this modification will significantly effect how long the gun would last.

plus, it will strip the piston if the bolt handle gets held up so it cant move while the gun is firing.

While getting my Thompson working again (I forgot to Fasten the Tappet Plate to the Nozzle last time I opened the gearbox.)
I also took a look inside the piston, to check if it had been punctured or damaged by the bicycle wheel crown tube I had put through the spring guide, (Have been using the Thompson quite extensively with the very same blowback method I announced in the thread which Charley added for you.) And it wasnt even scratched. Though this might very well be a "hole-in-one" case for all I know.
Listen to the experts and vets, theese guys has way more experience then me, I did it on my own wish, and I`m very satisfied with the added effects while firing my Thompson, though it may not be the same case for others. If you are afraid of adding blowback on your Thompson, you dont have to do it, out of, statistically speaking,10000 thompsons out there, maybe 10 of them has various user-made blowback mechanisms. And out of those 10, technically speaking, none of them has wear-free usage due to the extra stress and work which the blowback is adding to the gearbox internals and engine, for every bb leaving the barrel..
Sincerely Yours

although this may not be possible but i wonder if there is a way that the bolt stays back and still have blow back.

Well, that is a good question, and theoretically, it is possible.
Let`s say we do the same as in the bolt mod mentioned above. Only this time, the gearbox is a open piston type (Which is yet to be made for what I know.) Meaning we need to be cock the bolt once before firing, just like for real (Example: Mag is empty, open the bolt, insert full magazine, resume firing.) We fasten the blowback pin to the rear of the piston, and thus, when firing, the blowback pin goes forward, with the slacked fishing snare following (Which I am using because it is strong.) the bolt spring drags the bolt forward when the piston moves forward (Very much like when you manually drag the bolt back, and then release it.) which is pushing the air out of the nozzle, bb leaving the barrel. The Bolt then moves backward, the blowback pin and the fishing snare thus dragging the bolt backward. But this would require heavily modified or custom made gears and piston to withstand the continous pressure of staying cocked (Or tooth`s on the gears will break.) And the nozzle and hopup assembly would have to be made out of a very durable metal, because the nozzle would be slamming forward towards the hopup assembly with the equivalent speed and force of the spring and piston. It is possible, but would be very hard to do. Perhaps a Gas-AEG hybrid gearbox could be the solution? AZR is, to my knowledge, currently able to do hybrid modifications on gearboxes. But when the bolt stays open, you risk exposing the gearbox to unwanted elements like rain, dirt, and mud, and as we all know, blowback modifications on AEG`s (Any AEG.) whether we want it or not, always brings more wear on both gearbox, motor, and bolt, as well as the receiver.
