I would like your opinion and feedback on these USC aftermarket picatinny rails. Do they hold up well and how are they compared to HK factory ones? How much weight do they add to the USC?

Thanks in advance, guys!

Like all products from HDPS they are very nice and fit perfectly. With that said, I have one set of these, and one set I paid around $30 for, neither have failed and both work 100% The finish on the less expensive set is not as nice, but for a gun I shoot that's not an issue. The other difference is the HDPS set is rounded.

I have them and like that they fit snug to the receiver. The hk ones leave a gap (as seen in the hk catalog) and I did not want that. I recommend them.

I just bought a set but I haven't installed them. They are very solid and machined and finished well, I must say. They do weigh a bit more than the HK ones being that they're solid aluminum.

i have the long hdps rail, and the hk shorter rails. The hdps imho is better. i mounts perfectly flush to the gun, where as the hk does not, also the corners are rounded off a bit, the hk's are a little sharp.

That pretty much sums it up. I'll pick up a set of these rails for my new, in-bound USC. Thanks so much for your feedback and opinions.
