It is a full-sized duplicate that weighs about what an actual one would weigh and is constructed in the identical method. The majority of the gun is steel, and the grip panels and decrease receiver cowl are plastic — the true ones have been Bakelite, a primitive molded plastic. 

The MP has an under-folding inventory, similar to the true one, and for an grownup, I discovered it fairly pure to level and shoot from the shoulder. The sights are fairly correct, and this gun printed one of many tightest 20-shot teams of the take a look at. It got here in second to be used on the carnival star shootout, however didn’t lag by a lot. Its spring-loaded journal holds 52 BBs and a pair of CO2 cartridges at a time. You’ll be able to anticipate about 150 photographs earlier than the CO2 begins really fizzling out.

The charging deal with locks the bolt again like the true open-bolt design, and the bolt cycles with every shot. That does rob some CO2, however it’s price it. In actuality, it in all probability doesn’t really feel a lot totally different than capturing an actual MP-40, as a lot of these 9mm sub weapons are fairly controllable. Most of the Umarex WWII-era replicas are top-quality BB weapons, and the MP is among the best possible.

This full auto BB gun seems to be to be at the least partially impressed by the white Kriss Vector CRB, however there are some design variations, too. The ST-1 is a compact BB gun with a telescoping inventory and modular barrel design. In brief configuration, the top of the .177 cal barrel is shrouded with a three-lug mount like what you’ll see on an MP-5 or semi-auto SP-5, and the ST-1 has a 13-inch, quick-detach fake suppressor with a barrel that mates as much as that of the one on the gun — successfully lengthening it.

The hopper holds about 300 BBs, and to cost the journal, merely draw again a tab on the hopper, shake the 25 BBs into place, and press the rod again into the journal. The spring-loaded design retains a gradual stream of BBs feeding, and it’s the quickest of the total auto BB weapons to reload. The one draw back is that the hopper door on mine finally wouldn’t keep closed, so I needed to safe it with a bit of tape.

Bang-for-the-buck, the Umarex Legends Thompson M1A1 is hands-down one of the best ways to get a Thompson submachine gun as an grownup — or at the least get a style of what it could be like. This full-auto BB gun is one other in Umarex’s glorious classic duplicate collection, and it’s the best-shooting one which I examined. That is one which doesn’t intently match the load of the true mannequin, however an actual “Tommy gun” weighs 10 kilos empty, in order that’s comprehensible. In any other case the M1A1 is fairly rattling real in its recreation of the unique.

This BB gun mimics the open-bolt operation of the true M1A1, and the bolt drops ahead and is blown again with every shot, similar to the firearm model. It sports activities life like controls together with a security lever and semi/full-auto selector. It’s obtained wood-pattern plastic furnishings that’s actually the one draw back of the gun. I by no means encountered any issues, however the hole plastic doesn’t present the real really feel that a number of the different fashions have. I’m slightly paranoid about breaking it.

The steel receiver and journal are sturdy, and you will get further magazines for it — every of which holds the 2 CO2 cartridges and a loadout of 30 BBs. This full auto BB gun has a screaming quick charge of fireplace. I admire the nod to realism from Umarex by regulating the speed of fireplace of every of those vintage-design weapons to comparatively approximate that of the true McCoy. Not solely is the speed of fireplace quick, the M1A1 is absolutely correct. It printed the tightest 20-shot group of the take a look at, and I used to be capable of simply take a giant chunk out of the carnival star on the first whack.

It’s a part of the Legends collection of historic firearms that features the Thompson submachine gun and the German MP-40.

The Umarex M3 Grease Gun is a heavy, well-built BB gun. It weighs 8 kilos and is primarily steel. Not like many different BB weapons, the M3 feels sturdy. It additionally shows nice consideration to element like imperfect mock welds the place the true M3’s stamped components have been welded collectively. There’s a flip-up mud cowl and a thumb-cocking recess within the bolt. It has sling mounts the place WW2-issue net slings could possibly be hooked up, and easy, fastened sights. 

The facility behind this BB gun is within the journal, which holds two CO2 cartridges and a loadout of 60 BBs. I discovered that the Umarex/Hornady BBs and ASG Blaster BBs functioned finest. The Crosman Copperhead BBs generally didn’t feed by the journal easily. Whereas firing, the bolt truly cycles, then drops ahead when the final BB within the journal has fired — similar to the true open-bolt M3. This operation robs a number of the CO2, however you’ll be able to often get by about 180 BBs earlier than you should swap cartridges. 

Sticklers will level out that the speed of fireplace is way quicker than an actual Grease Gun, however should you can’t overlook that, you’re a Scrooge. I discovered it to be a very good stability of velocity and precision. Due to its sub-gun standing, I examined the M3 for accuracy at 7 yards, and it held a good, however barely off-center group. Irrespective of, one can merely strafe right into a row of empty cans and clear home. That is actually an superior, insanely enjoyable BB gun that can make anybody smile.
