Best left to a gunmsith.
M41 is not a standard airsoft model, did you mean a different one. Also it depends who makes them.
The M41 Walker Bulldog Light Tank used a 76mm main gun. US forces did not use this tank in Vietnam, the Bulldog was deployed by ARVN (South Vietnamese Army) armor units.
Which sight? most have a switch or rotational switch that can be turned off.
No, it was replaced by the M48 and M60 in the late 1960's and early 1970's. A few small and poor countries may still use M41's, but most got rid of them in the 1990's. It is hard to find information about tanks that are used in small numbers in other countries, but some possible countries that might still use them are the Dominican Republic, Guatemala, Lebanon, Somalia, Spain, Tunisia, Uruguay and Vietnam. One country that FOR SURE still uses M41's is the Chinese Army. They have around 500.
With the exceptions of the US M113 ACAVs and M41 Walker Bulldog light tanks, it was as "historically" correct as funding and script/military technical advisors could make it. The M113s should have had ACAV sets on them (if they were missing) and the US didn't use M41 Bulldog tanks, the ARVNs did; but it is understandable that the producers couldn't get ahold of M48 Patton tanks. Full Metal Jacket was the same way, they used M41 tanks too, when they were supposed to be M48 Pattons. Also, "Full Metal Jacket" was less historically correct than Hamburger Hill was.
MacArthur (again), Ridgeway, Walker (had the M41 Walker Bulldog light tank named after him).
In some roles, it was replaced by the M41. As a main battle tank, it was replaced by the M47 Patton.
on top of the scope is the brightness and on/off switch. the top of that comes off when you twist it and the you put your batteries in there
US supplied the RVN with M41 Walker Bulldog light tanks, A1 Skyraider attack planes and F5 Freedom Fighter jets.
None. The only two galactic object in the constellation are:- * M41 is an open cluster * NGC 2362 is an open cluster
Australians drove Centurion tanks. Americans drove Patton and Sheridan tanks. The ARVN drove M41 Walker Bulldog light tanks; and the enemy, the NVA, drove PT76 Amphibious light tanks and T55 medium tanks.
There were many notable actions that happened in 1765. Since like astronomy, I like this one . . . Charles Messier catalogued M41 (galactic cluster in Canis Major) Also, Britain passed the Quartering Act, requiring colonists to provide temporary housing for their soldiers.
