Hi thanks for looking, i have my m4 cbqr for sale , i have used it a handful of times but need the money to fund another project, i have had an npas valve fitted and a pink flamingo bucking fitted, there is a small amount of usual wear and tear marks on the gun which you would expect , i have removed the front iron sight and 3d printed a "gas block" to hold the hand guard on , it just needs 2 grub screws to secure it in place properly ,but i will include the original iron sight with the gun anyway, and i have also 3d printed a thread adapter as the outer barrel is a c/w thread and most stuff now is a ccw thread, you can buy metal thread adapters but when i was looking for one there wasnt any in stock anywhere.

The magazine is included with the gun, but the screw that holds the feed lips and gas route rubber in place has snapped and some of the thread is still in the magazine, you may be able to find a shorter screw and it will work fine, but ive not got the time to sort it so im throwing it in for free essentially.

If you have any questions at all or want any more photos etc please dont hesitate to ask

The price  inc g&s and P&P Hard case is included in the sale as i will ship the gun in the case. thanks for looking,
