KWA LM4 Magpul PTS Edition with upgrades

KWA LM4 Magpul PTS Edition with upgrades

I am selling my beloved KWA LM4 Magpul PTS edition after 4 years of ownership, due to lack of game play.

It was my first GBBR and I have wanted to get the closest thing to the real steel AR15.

KWA are known to produce training equipment for the US law enforcement and military and I wanted a bit of that in my mil-sim games.

Check out their promotional stuff here:



It has the full Magpul trade marked polymer furniture such as the front hand guard, pistol grip and the adjustable stock.

The lower receiver also has the full Magpul trade marks as can be seen in the photos.

Upgrades included are as follows:


  1. Maple Leaf Hop unit and Hop rubber
  2. Tight Bore Inner Barrel - 6.02mm
  3. PTS Ambidextrous Fire Selector (£45)
  4. Lightened Buffer Recoil Block
  5. Polished Bolt Carrier for smoother firing action
  6. Magpul B.A.D. Bolt Release Lever for quicker bolt release action using your trigger finger (£35)
  7. Madbull Troy Industries Licensed TRX Battle Rail free floating 13" handguard (£68)
  8. MBUS copy front and rear sights (£12)


Also included in the sale are the following:

  • Original Magpul Handguard assembly with the mock gas tube and outer barrel fixing nut
  • 10.5" outer barrel modified with TDC (Top Dead Centre) hop adjustment for CQB use. (£22)
  • 10.5" inner barrel with the original KWA hopup unit
  • Original Rear ironsight to go with the original front iron sight
  • Red dot sight with 2mm clear polycarbonate protective screen on the cover. (in case the glass gets shot) (£16)
  • 3 No. extra magazines - no leak, made by PTS (£39 each = £117)


The upper receiver was made in three pieces (due to the early design by KWA) and was prone to creaking with use. I have fixed this with metal epoxy to stop that happening.

Also fixed the Bolt Catch as per this video:


I found this guy excellent for knowledge and instruction for fixing and upgrading the LM4.


I also have the Angry Gun high recoil spring (unused) as a spare too.


Currently running around 320-330 FPS with Green gas.

It has the same issue that all GBB guns suffer from in the cold weather. Otherwise, it run well and I will miss playing with it.

As I don't play as much now due to work commitments, it will have to go.


Will be sent in the original packaging with the 2-3 days courier service. Price includes the P&P.
