Ooh, sorry I didn't get back to you sooner.
The rifle above is a JDL PTR-91 that I purchased from Impact Guns - buying from Impact was a bad experience and I won't do it again.
It was in the lower serial number range, the buffer was non-functional and at 50 yds, the best it would do was about a 5 inch group at 50 yds - and I had to aim about a foot to the right of the target because the sights were so far off they couldn't be adjusted anymore. Some guys had good luck with these rifles, others...well, they had luck like mine.
But I don't give in easily, so...
The barrel was a JLD 24" heavy barrel that I purchased from Recon Ordnance. I think these are all sold out. I talked to JLD and they said that they only made a small run of these due to lack of interest. It's not as heavy as an actual PSG-1 barrel, nor as long of course, but it is longer and heavier than the typical HK-91 and clone barrels.
I sent it to SRT arms (the suppressor mfgr.) to have it cut down and threaded. I wish I had left it about 2" longer (22 inches) but he talked me into cutting it to 20" The flash suppressor is a smith vortex in 5/8 X 24
It was mounted by Pat at Pat's Custom Firearms. He does decent work and doesn't take too long.
I knew nothing about these rifles when starting this project. The barrel needs to be mounted by pressing it into the reciever and drilling/pinning. Then it is test fired and the bolt gap needs to be checked to verify it is within spec because the barrel will settle in a little.
Once I got the rifle back, I sent the trigger group to Williams Trigger Specialties and had it modified to a "set" trigger. Basically the pull is lightened to about 5 lbs with a "set" position that lowers it even further to about 3 lbs.
The stock is an actual H&K psg-1 stock. These are pricey and difficult to find.
The grip is a custom order Ambidextrous ergo grip from Falcon
A.R.M.S. scope mount
IOR Valdada Rings
IOR Valdada 2.5-10 X 42 Illuminated stadia line scope.
I have a wide handguard on order for it and a new bolt-head/locking piece, as I think some of my severe recoil issues and brass getting almost ripped apart are due to an inferior quality bolt/locking piece - just a guess. That stuff is on order from Top Notch. I wish I had ordered from someone else, they flat out lied to me about shipping time. But that's nothing new for them from what I hear.
There are very few reliable, honest businessmen in the HK world unfortunately, from what I've seen, almost all of them run a scam from time to time. You just have to do your homework, resist being impulsive and be willing to be extra patient to make sure you are getting the best quality.
