Everything!!!...the weight is pretty cool...exact replica...mine is a blast!!! i had no jams like i read in a lot of reviews...think most are user error in loading...with practice you can get pretty good at loading by shifting the clip back and forth while pouring bb's in

i found using two dimes in between the cartridges works great to puncture both cylinders...listen closely for BOTH punctures...they do not puncture simultaneously

Really Really fun...buy a extra mag...lol

Solid, all metal...

Magazine gets jammed every time...every burst of BBs. Have to take it out and re-align BBs before every shot. Very poor design

It is fun to shoot. Feels and sounds like I hoped it would

Until I arrived at the solution below, I hated refilling the bbs.

1. I have this sub machine gun. I loved shooting it. I hated loading it. Here is what you need to know. Buy the black plastic container filled with bbs with a narrow (self loading ha ha) top. Get a magnetic pick up stick. Order a pizza. When you are through eating the pizza, cut the top off of the pizza box. You now have 2 bb catchers. The spring on the magazine will over time stretch so you can hold it back with your left hand.(thumb) Hold the magazine up at a slant (High on the left side)over the middle of the pizza bb catcher with your left thumb holding the spring back. Pour bbs into the hole from the right side of the hole, Unscrew the top of the black bb container, pour bbs back into it. Use your pole magnet thing to pick up the few that escape the bb pizza catcher. Now you can reload quickly and enjoy your gun. If your cartridges are not opening, put a dime in between. If they are not sealing when tightening, take it out.

Like the weight.

Make this gun work

I had nothing but problems with this gun. It would dry fire most of the time. I sent the first one back to Pyramyd and the sent me a "new" gun, it was not new. The gun they sent back was probably my original gun. This gun was just as bad. I tried full mag and half full mag. Single shot and burst fire. It takes at least 2, CO2 cartridges for a full mag. I would not recommend this gun.

I like the weight.

Make this thing reliable

I could not get this gun to shoot , but maybe 50% of the time. I sent back to Pyramyd. They told me they were sending me a "new" gun. The replacement was not new. It might have been the same gun, which still does not shoot. Does not matter if the magazine is full or half full. I am very disappointed with this product and the way Pyramyd handled my problem. Pyramyd has lost a customer.

The weight of this gun is amazing it just feels right in your hands the fire rate is almost spot on

The mags jam occasionally

Amazing product here

This is a lot of fun to shoot and pretty accurate considering it's a smooth bore Cartridges seem to last for about 3 full magazines.

As in, it seems,all magazines, MP40 Thompson , the teeny tiny detente that mush be retracted to load is a bit of a challenge for big fingers. You need to let your fingernail grow so you van hold it back. There is plenty of room for a bigger detente or even better a small notch to lock it in.

The option for auto and single shot..awsome

Full Auto is an absolute blast. No pun intended. Rips trough a full mag in seconds with no problem "as long as the BB's are stacked correctly in the magazine". The airgun fires from an open bolt just like the real thing.

Not much that I would change.

Alot of people are having issues with jamming. As long as you load the magazine properly. You'll be fine. The 2 co2 cartridges last a good amount of time. Full or semi auto. Fyi it does fit airsoft mock suppressors or flash hider.

Everything about the gun excites me. Great replica.

I found the magazine to work well with Excite Smart Shot and Dust Devel BBs, as well as steel ones. See my comments on the magazine review.

Great looking and feeling replica, a ton of fun to shoot! The weight and feel of this thing is satisfying, and I really like the charging handle operation and that when the mag is empty it does not fire, just like a real one. Rate of fire is just right.

Not much, though a hold-back notch for the BB follower would be nice, as would on-board storage for the hex wrench. However, I came up with a solution (see below).

Use a piece of decent wire clothes hanger to make a magazine follower hold-back tool. I made mine with a design to hook over the bottom of the mag so I can easily load BBs. Also fashioned with a loop for key ring/carabiner to keep it handy. A little heat-shrink tubing helps protect the mag and gives a better grip on the tool. For the hex wrench I used some heat-shrink tubing and good, flexible wire to add an attachment loop. Now I can attach the wrench and loading tool to a lanyard and keep them handy with the gun, and they are not getting lost.

Everything. Looks real. Feels real and a blast to shoot on days when I can't make it to the range.

Needs a tool to hold the magazine follower.

Use new bb's. I first used old ammo that was not as shiny as new and they would not follow in the magazine. I tried new bb's and have not had a problem with jamming. Even with full magizines.

This is by far the most FUN GUN I have ever shot..The quality is Awesome as well.Its a handsome gun...

Maybe Make it 90 gram c02 accesible

Its not really a sprayer ,,In 5 round bursts at 65 feet its very accurate

scurrying rats hard to hit with air pistol. problem solved !

tighten up shoulder stock a little

funnest gun avalable

Does what is advertised to do

More fps

Fun to shoot

Great back yard fun!

Looks like the real thing.

Magazine should allow BBs to slide inside more freely. The BBs get stuck inside the magazine and stop feeding properly.

When the automatic is selected it feels like a real machine gun when firing just not as hard.

arrived on time and product is as described. super fun to shoot .

add a notch in the mag to hold the loading gate open.

requires steel bb"s

Took me a while to order this gun because I didn't believe it would be any better than the UZI. Good surprise, besides being a well made replica it shoots very well semi and full auto. Full auto short bursts are precise and tight (2.5-inch group) at 24 feet. It doesn't have those horrible white warnings all over the gun and it stops after the last BB.

Nothing

It is accurate at 24 feet if you put the front sight close to the right rear side and the rear sight flipped up. I painted the front sight in white and the rear in green. With 50 BBs in the magazine I had 200 shots per 2CO2, or 100 per CO2. Using 3 or 2 magazines with one CO2 each and cycled through them keeps the power in the high level.
It has a 40 mm CCW muzzle thread.

This thing is an ABSOLUTE BLAST!!!!!!!!! Well made fun gun to fire for effect for cheap money.

Nothing I can point to

Buy an extra magazine or two... buy a BUNCH of CO2 and quality BBs... DO NOT let your friends borrow it... You will not get it back in short order
