  • Retractable stock allows for a more compact overall size and lets you adjust the length of pull for ideal comfort

  • Internals feature 8mm bearings, CNC-machined spring guide & nozzle, as well as full-steel gears
  • Integrated bipod provides adjustable support from fixed firing positions

The Mk48 is a 7.62x51mm medium machine gun designed and produced by Fabrique Nationale in conjunction with the United States Special Operations Command (USSOCOM). Intended to replace the M60 series of machine guns as a bridge between the M249/Mk46 series of 5.56x45mm light machine guns and the M240 series of 7.62x51mm medium machine guns, it successfully entered service with special operations during the early days of Operation Iraqi Freedom and has continued to be used by units such as the US Navy Seals, the 75th Ranger Regiment, and Army Special Forces "Green Berets".

The Lambda Defence Mk48 MOD 1 faithfully recreates every minute detail of the real deal to incredible degree, starting with its dedication to almost perfectly replicating the weight, size, and feel of it. A full steel construction makes this one of the toughest airsoft machine guns on the market. Upgrade from your current gun to something that will turn every single head on the field!

"What can I say… This is one of the heaviest LMGs that I have owned. It weighs as much as two M60 E3s that are currently available in the airsoft world. It came with the folding M4 style stock and NOT the MK style full stock that is pictured above. I just need to buy the flash hider that’s supposed to come with it because the internal barrel is exposed with the generic plastic one. Don’t let that deter you from purchasing one. This is one fine piece of BADA**ERY! You’re a deserving person that has to be rewarded. I got mines. Get yours Papi. It’s calling you!

"Was so excited when i saw a MK48 finally available for retail. The only other MK48 being the $1k VFC this is a “bargain”Very happy build quality is the absolute best of any support weapon I have owned. Just so everyone is aware mine came with the folding M4 style stock vs the MK style full stock.
Performance out of the Box is acceptable 297fps w .32s.
Magazine holds over 6,000 rounds
Mixed feeling on the proprietary HopUp unit
But the use of the SAW style gearbox was great
HEAVY 18 pounds unloaded but the quality exterior wise is amazing lot of small details like the ejection port opening. Compared with the A&K and CA saw the lower hand guard and receiver have no play at all. Only play is a bit of movement in the quick change barrel.
Overall I would recommend it for the external quality I do plan to go HPA but definitely on the high end for pricing. If you want to run a MK48 replica look no further objectively though a standard saw is less expensive and will do the job.

MK48 mod 1 with retractable stock

This is the second mk48 I've purchased from Lambda and was/am extremely happy with the first one, which I still own. This latest run which was stocked in July 2023 is substantially lower quality. The finish, materials, parts and markings are all sub par this time.

Here are the issues I experienced out of the box:

Wire harness for the box mag was not routed through the side of the gun as SHOWN in the pictures. It was routed through the top and SHUT in the feed tray cover. This crushed the wire and caused the gun to not function out of the box.

The body, feed tray and/or cover are out of spec. The feed tray will not fully seat without wiggling back and fourth and forcing into place. This prevents the feed tray cover from closing.

The product listing claims the product has highly accurate trademarks but the gun reads mod 0 and not mod 1.

The materials are not as described as well. The barrel is now all aluminum except for the gas block. The originals came with a steal barrel. Many other parts now seem to be of a lower quality but that's not stated in the description or reflected in the price.

I should have immediately started the return process with Evike however I chose to try and fix the issues as these are almost always out of stock.

For the price I would highly discourage anyone from purchasing one of these.
