Ok, so I went shooting last weekend and everything went well. Only problem I experienced was zeroing a Nikko Sterling scope that was fitted to an FX airgun previously, using a faulty bore sight.

I also need to add that I only realized I left my magazine bag in the safe when I started unpacking at the range. So all of these were single shots. Which sucked. But the trade-off was that I could lean into my shooting bag more effectively.

Rifle is a Vektor production LM5 with a 1:9 twist.


This is the scope fitted to the rifle. Nikko Sterling.


Grouping at 50m with handloaded Hornady V-max rounds. Under an inch.


Grouping at 100m with purchased PMP 55gr FMJBT. Two sets of 5 rounds, aimed at different targets. 3.5" grouping on 1st set, 3" grouping on 2nd. The dust cover was removed and replaced between the two sets. This was done to prove that the zero would remain the same after disassembly. I was shocked at the difference in performance regarding the groupings. I was always under the impression that boat tail projectiles would be more accurate than flat base rounds, but experience has proven different.

I'll upload a video soon.

Here's the video as promised:


I've made arrangements with a local entity, so I'm able to ship it at $80 a unit. The shipping is still $35 a unit via DHL, as I don't have a contract as an exporter with them yet. More than happy to make use of another courier company if you'd like to arrange pickup.

And here's a client's set that's been installed. The front rail's been cut at an angle and the welds made internally as per his request. Admittedly this looks much cooler than I expected, so I'll recommend this for other installations going forward:

Reapplied the parkerizing on a few clients' sets before shipping them back. Will post a few pictures as soon as the rails have been fitted.



PS - The carrier with the oversized charging handle; that was as received from a client. I did not make that modification. A little big for my taste.

After completing a larger order last week, I thought it appropriate to give a bit more detail on the installation process. I'm going to post a video in the near future, but here's a few pictures explaining the process.

First we drill holes into the gas tube rail. This is so all welds are in the inside of the bracket. Looks a lot neater this way.



Next we sand down the sections to which the brackets are going to be welded. Both sides of the dust cover, as it will be spot welded.



Then we set the parts to be level with the receiver and clamp them in place.

From here the parts are removed and the actual welding takes place - TIG welding for the gas tube with the aforementioned holes and spot welding for the dust cover. I place a rolled up copper sheet on the inside of the gas tube to absorb excess heat and prevent any bumps on the inside of the gas tube - an annoying lesson learnt.

After this any burrs need to be removed. As with the sanding, I have a rotary tool that's just plain amazing for this.



With that the parts are sandblasted and parkerized. After the parts have been in the solution, we drench them with oil - lanolin or Q20 - for at least 12 hours.



Then finally, we assemble the parts.

The final product:






And the shorter version, as fitted to the LM5

The installation instructional video.


Total about 3 hours of labor for myself for installation, obviously spread out over several activities.
