Decided to sell my BCM4. 
I bought the gun second hand from these forums as a standard M4. I then customised it with the following:

 

- custom BCM Haley Strategic engraved and laser etched Lower received.
- polymer trigger guard

- BCM style pistol Grip

- Keymod rail with grip

- Genuine BCM keymod Rail covers

- G&G knights type flip up iron sights. I drilled open the rear aperture for faster target acquisition in airsoft.

- Magpul Style MOE stock

- Magpul Style ASAP sling mount at the rear.

- Magpul style front sling mount.

 

long inner barrel installed to sit inside supressor.

electrical tape on buffer tube to reduce stock wobble. 

 

the gun works very well but it fires when on safe. So it may need a new safety catch... im not a GBBr expert so didn’t want to go faffing internally. 
it shows signs of wear and tear. I’ve only used it for garden drills, never skirmished. The FPS is more in line with a training rifle or DMR so if you intend to skirmish this rifle, it would benefit from a semi-only mod.

 

it was kept as a collector/play piece so not fully tuned for skirmishing; but it easily could be. The new selector switch modded for semi only would solve all issues.
 

comes with one CO2 magazine.
