Lambda Defence x B&T GHM9-G Gas Blowback Airsoft SMG (Model: Short Version / Two-Tone)

"10/10, have no disappointments so far.

"This thing is awesome. I have bought two with plans to run a small barrel and longer barrel design. People get fussy over fps but if you extend barrel you can solve that. You can find replacement nozzles for now but other internal parts I haven’t found. It’s just a fun gun - time will tell with the durability - I have put atleast 3k rounds through it between both a gas and hpa set up and nothing is slowing down. Extending the barrel was extremely easy and the hop up design works and keeps the dial where you set it.

For the price I think this is a great small smg that you can upgrade and customize the way you love it. Easy design and once replacement parts are made you can feel more comfy to challenge the setup and fix and breaks.

"Ive fielded mine twice and it works vreat i got it on a epic deal a a coupon so im happy with the price i paid
Out of box you have to remove stock plate to install charging handle front handguard was loose 2.5mm screws were loose
shooting 0.20g at 290-300fps with the stock mag
Pros
Easy to tear down and maint need a punch for pins
Decent fire rate 11.2rps w/ 130psi GG at 85F
Works with most glock mags *lock on empty iffy on some or tight fit*
Easy access dial hop unit *have to rotate about 180 before hop engages*
Standard Gbb barrels and buckings fit easily
Easy to short stroke

Cons
No internal replacement parts atm *unit has only been on market a year*
Plastic outer barrel is constantly loose and has poor fit
The carrier doesnt always seat down due to weak recoil springs *hoping for increased strength aftermarket down road*

"This is a wonderful starter smg for people getting into Airsoft. This is the first smg I have ever bought and it is worth the money. After firing it some things got loose like the grip and hand guard but if you have any allen keys laying around that should tighten everything up.
Pros:
Fast fire rate
Good starter smg
Easy to chamber
Quick disassembly (if ever needed)
Good fps
Works with WE-tech Glock mags
Cons:
Weak springs
Hard to put on charging handle (almost broke the springs doing it)

"Absolutely love it! It's super quick and responsive and very accurate with 28g bbs, can definitely hop heavier, do some research before buying mags though

"Owned for about a year and a half, finally doing a full review.

Cool little project gun, even better with HPA. By itself it's extremely unexciting because of how barebones it is. It becomes more fun when you install one of the handguard extension kits and a stock.

My upgrades:
INTERNAL:
-Angel Custom 6.01mm Tightbore Inner Barrel (160mm, same as the KWA MP7)
-Maple Leaf Autobot Bucking (80 degrees, VSR10 and hi-capa compatible)
-Custom short-stroke kit that I made myself (literally just a centimeter piece of clear inner tubing, one for each recoil spring. and yes, the bolt will still lock back on empty if you do it right.)

EXTERNAL:
-Lambda Defence Standard Rail Kit (fits the 160mm inner barre perfectly)
-Lambda Defence 4 Position Collapsible Stock
-Custom ambidextrous charging handle mod that I made myself (Two charging handles cut in half. A Lambda folding one in the left side of the receiver, and the standard one on the right)
-Some garbage umarex RMR
-Primary arms HPA adapter (w/ regular PTS EPMs)

PROS:
-Extremely buildable towards whatever playstyle you run
-Full-ambi controls (except for the charging handle, but it's flippable) (see my external upgrades)
-Kicks alright for its size
-Light as it is, still pretty light even with the extra stuff
-Fully compatible with AAP01 mags, stock mag works great as well
-Shoots STUPID far with .28g plus the upgrades above
-Good RPS by default, even better when short-stroked (see cons)
-The metal receiver is *probably* a good upgrade but I haven't bought it. Just read its reviews before you buy it and make sure you know what you're doing.

CONS:
-Extremely boring by itself
-The screws suck (they're all allen keys and they unscrew themselves over time. Blue threadlocker helps a lot)
-Fires on safety if you pull the trigger hard enough
-Mags are stupidly expensive (it's a GBBR, just run HPA if you care)
-EXTREMELY weak recoil springs (not very satisfying to charge and reload the gun)
-RPS gets slower when using heavier BBs (yeah...)
-Bolt catch has no spring (it will auto-engage when held upside down)

FUTURE PLANS:
-Would like to finish externally kitting it with a tracer, foregrip, light, and a better red dot
-Maybe get a bigger stock pad since the one I got is kinda small (i'm a very tall person so who else really cares)
-New nozzle, just to be absoutely sure that the HPA pressure won't kill it (even though it runs great as is. just to be safe)
-Heavier recoil springs to fix that stupid RPS issue

TLDR:
Boring by itself but great if you wanna build it into whatever you want. Run HPA and you won't go wrong with this one.

"Not shooting good like no power, fullauto issue too, the mag don’t hold a gas at all, look good and feel good but I sold to my friend in 100 dollars.

"This thing is killer for what you pay. Ran a 2 day milsim mainly running this with little to no issues. Range, reliability, and accuracy was more than I expected out of a 1j gun and was easily able to make 150-200ft shots with .28g bbs
Pros:
-Mag comparability; used we, Tm, Vfc, and spartan Glock mags
-Gas consumption. It will cycle all the way through and lock each time
-Weight
-Hopup. Easy dial design requiring no special tools to adjust
Cons
-recoil springs feel week
-proprietary nozzle (if it breaks I haven’t found a replacement)
-hand guard wobble
- stock mag. Mine came leaky and improperly assembled with a stripped base screw which required some time and machining to fix
-bolt. Due to the week springs the bolt won’t always seat all the way in battery, a common fix is to short stroke the springs

Over all awesome replica and it will definitely be a go to for the summer

"I've had this for a few hours now and after playing with it I've had several issues, first it would not cycle magazines that good, sometimes it would double cycle or not cycle at all and this was with my aw 50 round glock mags and the mag it came with, second the handguard is very wobbly making it feel cheap. It's not a bad gun I just wish it cycle rounds better
