PTS UBR Stock (image from AirsoftGI)

The PTS UBR Retractable Stock. Quite a mouthful. But I can guarantee you that you will get a mouthful of saliva when you see it in person, on your Armalite. The dimensions on the stock is significant; much bigger than your average butt-stock. It works on a slightly different principal compared to other stocks I have encountered, whereby the lower half of the butt-stock is retractable, not the whole piece. The plastic is not normal plastic nor is it ABS plastic; it is thick, hardened polymer plastic which is not gonna break on you anytime soon. Most probably it will outlast the ABS plastic on your piece. It comes equipped with a six-position retractable lower stock for long range aiming with the indicator located at the bottom of the outer stock post, and weighs in about just under 500g.

When you receive your PTS UBR package, you will see these items inside:
1) The lower half of the stock
2) Two stock post; one for GBBR and the other one for AEG
3) Two pieces of cheek rests
4) A set of screws

Disassemble your stock post. You should find this piece on your armalite replica.

This part is vital to make a good fit onto your mouth-watering brand spanking new PTS UBR. Should you encounter some difficulty in placing the new stock, this should be the problem area. What needs to be done in the following mod should be done carefully so as not over-do it, or injure yourself in the process. This part requires a sharp knife.

First of all, mark the area that you will need to retrofit the new stock post in by pressing the UBR stock onto the original part leaving a mark as shown.

This is the stock post for AEG.

Then, carefully shave out the new area slowly with the knife to allow a tight fit for the new stock. Get this wrong, and your PTS UBR stock WILL wobble. So please pay special attention when shaving the area out.
