This little guy really made a difference, and helped me achieve proper length for my Hera CQR stock. Suggest you order this if you are 5’10 or greater, as you most likely have great arm length than the Hera stock comes adjusted to.

Hera arms spacer works as advertised, gave me the correct length of pull, no complaints there. My one complaint is there were two distinct options, new, and used with scratches. I specifically ordered the new one, but the one I got has a scratch on both sides. Doesn’t affect performance in any way, just kind of annoying considering I’ve never had any problems with opticsplanet in the past. I’m only a few bucks, but it’s about principle.
Pros:
Adds length to stock.
Cons:
Anodization can scratch
Best Used for:
Adding length to stock
Would recommend: Yes

I finally was about to make my AR-10 featureless after having one of the mag lock installed to be California compliant. The spacer that comes with the CQR AR-10 was too short. This gave me a comfortable length of pull for the stock. I was hoping to combine the spacers, but the included screws were not long enough. Still a great option for California Ar-10 owners.

I have the HERA 15mm and 30mm spacer. I bought the 45mm to lengthen the stock to make the rifle more comfortable to shoot. The spacer does exactly what it says in the description. Took 5 minutes to install it.
