I have an M1A1 Umarex also, an MP-40 and an M3 Grease gun. When I first started I had the same issue, I solved it by libecating (of course the Gun itself) the BBs before I loaded the BBs and both sides of the top of magazine. Although I use a much thicker silicone oil that WD-40 specialist Silicone. A minimum of 100 CST. Never had another problem wit feeding BBs from the Mags on any of the guns.
Have toy glock 18c And desert eagle Golden and glock is black and green have replica glock 34 and glock 17 keychain plus berreta and ruger p320 not sure bout glocks has mini bullets 4mm not sure if fires Chinese man said that doest why does cock back and can take apart etc
WD40 makes a product called WD-40 "SPECIALIST SILICONE" the can looks like a WD-40 can except for the large lettering "SPECIALIST SILICONE" on It and that is what he is using. The cost of this can is about $7.50 U.S. a can. Holds 11 oz. For 100% silicone that is pretty cheap, that is about 0.68 cents and ounce. That is a real deal, Pure Silicone oil is much more expensive of course. WD-4- is a very thin silicone oil about a 20 CST rating. DO NOT USE regular WD-40 to lubricate ANY AIR GUN. WD-40 is made from petroleum and that will destroy the rubber seals of the air/C02 chamber. Silicone oil does not affect rubber, synthetic rubber, plastic, metal etc.

Thompson is actually a nicely balanced gun, the MP40 is total opposite and not balanced at all. Just like the original guns in WW2.
It was way ahead of it's time.
huh we used to drop our guns in ww2 and pick up german guns because they were better
Shit...they have 90 day warranties....you should have used the warranty for the repair.
Try it in Spanish.

Wd 40 will mess ya seals up by a decent gun oil
They want you to use umarex brand steel bbs

That looked like WD40 you were spraying into the valve, That is noy silicone oil and will destroy your seals in short order.
