Over to you, /Dave.

This Walther LG55 is another used gun that I bought from a reputable seller on the Yellow Classifieds. B.B. asked me to share my impressions with you after I received it. For a lot of people here, this well be a repeat of how to evaluate a used gun. Most people here know, or at least have an idea, of what appeals to them before buying a used gun. Some don’t like to risk money on a used gun, which I completely understand, having been burned once or twice. For those of you that do take risks, here ya go!

This curly walnut stock caught my eye right away!

After my new gun arrives, I generally give it a once-over, looking for any obvious faults and to find out if I need to do any serious work on it. I was happy to get this rifle after delays by the shipping company. The wait, which is normally pretty hard, was extended by more than another week while the shipper decided where it was really supposed to go. When it finally arrived, I was like a kid at Christmas trying to figure out the fastest way to get my new of gun out of the box and out of the paper, tape and bubble wrap that were quite generously used.

After freeing up the rifle and then unwrapping the rear target site, which had been removed and wrapped separately to prevent damage, I quickly mounted the site and brought it into the bright kitchen light to show off my treasured wood to my wife. She said that it looks alive, like a fish swimming! A great improvement over, “I’m not interested in that stuff”! So, I took off down the stairs with a big grin on my face to my little 9.5-yard range to try it out.

The curl goes all the way through the stock.

Giving the gun a quick once-over to make sure all was in place and not loose, I broke it open and cocked it. Man — this thing is easy to cock! A six-year-old could shoot it if he could hold it up. My old bathroom scale says it takes 18 lbs. to cock, and it weighs about 8 lbs. Even at 8 lbs., it should be an all-day shooter for me!

Barrel patina.

I took a couple of shots at about 5 feet and then 15 feet to see if it would stay on the paper and to check function. “Check function”… uh-huh! That’s the adult way of saying, “I really can’t wait long enough to go over this thing in detail. I gotta shoot it NOW!” Yes, just under the surface, I’m still just a 10-year-old boy!

What you don’t see in the pictures is that the stock is scratched up. The barrel and compression tube are about a quarter to a third speckled with surface rust that’s not pitted. It’s more like the bluing wear from many hands, rather than neglect. Even with these faults, I’m inclined to just treat the whole gun with oil but not refinish it. Most of the scratches in the stock would vanish with a light sanding, but there are a few that would alter the stock’s original lines if removed. Since I’m not really a big fan of wood filler and refinishing over scratches doesn’t look right, I’ll leave it alone. I kind of like this gun the way it looks, anyway. It speaks of a long life of use and enjoyment that would be lost if I dolled it up too much.

One of the worst dents on the bottom edge of the stock. Some of the wood fibers are cut, so I don’t think this will steam out cleanly without leaving a hash mark. There are a couple more on the forearm that are as deep.

First results from my Competition Electronics ProChrono Digital chronograph with RWS Hobby pellets weighing 7.0 grains was around 412 f.p.s. Not that encouraging, considering a quick online search finds that LG55 rifles should shoot around 550-575 f.p.s. at sea level. I’m shooting at just over a mile high in elevation, so I don’t expect to ever make that 575 f.p.s. mark, but somewhere around 525 f.p.s. would leave me tickled pink! But, the rifle is shooting very consistent within a few f.p.s. around 412, so I added a few drops of heavy silicone dashpot oil to the chamber and let it sit a few minutes.

I checked the breach seal while adding the oil, and it looks like it’s in good shape, smooth and standing just a little above the surrounding metal. Tissue paper laid over the breach while firing confirms a good seal. If the tissue doesn’t move, there isn’t enough air leaking through to matter. No oil spray on the tissue is another good indication the breech is tight.

The oil in the chamber brought the velocity up to around 468 +/- 2 f.p.s. right away with no excessive smoke due to the low power of this target gun. That number goes up more after the gun has set for awhile, then drops back off while shooting. That’s still encouraging. Along with the smooth, un-twangy solid thwack when the rifle fires and no grinding with a positive click of the sear falling into place when it’s cocked, that tells me the gun probably just needs a new piston seal. The piston seal on this gun is synthetic, so the oil is just a temporary fix/diagnostic tool. It will need to be replaced to regain its velocity potential.

The difference on the target between 500 f.p.s. of the LG55 and 750 f.p.s. from an HW57. A faster pellet cuts cleaner and is much easier to score or measure when your target isn’t exactly square to the shooting lane. A slower pellet has more tear-out.

While shooting through the chronograph, I noticed that I’d run out of adjustment on the sight and my groups were still hitting an inch high and to the left. Oh no! Shipping damage? Bent sight? Major tweaking might be needed! Ok, calm down and take a good look at things. First, I sight along the compression tube and barrel under a light to see if it’s out of line. Looks pretty straight there. Check the sights. Tight and straight. Front sight is straight and the target insert is correctly seated in its notch, so on to the rear. The click adjustments run full travel on the rear peep sight, and it doesn’t appear to be bent. The sight base seems to be clamping the dovetails correctly. Hmmmm. Ok, loosen the knurled knob and take off the sight to examine it closely. All appears good, so I centered the adjustments, and the peep is right in the middle. No problem here. More thinking….

I decided to remount the rear site and noticed that there are markings and grooves on top of the rail. I lined up the front of the sight with one of those marks. Ah-ha! The knurled nut now travels much closer to the base when I tighten it. The nut has a collar that extends into one of those grooves, locking the sight in place! After tightening it up, I decided to take a shot at a new target. Nine ring! Another shot. Another nine, breaking the ten ring! Great, that was the problem!

In my over-anxiousness to shoot, I’d missed seeing the grooves while mounting the sight and it wasn’t seated properly on the rail. This is what threw off my point of impact. No barrel tweaking or major work other than a seal replacement is required! I’ve found a source for the seal and some other parts for this old gun at JG Airguns. I may make a seal mod with some Teflon round stock and a quad-seal o-ring (like I did with my TF99) if I can’t get this one soon enough.

Notice the horizontal lines on top of the compression tube, in between the dovetails. The front of the sight must be aligned with one of these in order for the locking collar (beneath the knurled nut) to slide in and out and secure the sight from sliding.

The trigger has a really long first stage, and there’s even a little slop in the trigger blade before it starts. I need to do some more research online for adjustment procedures to see if that can be reduced. If not, I’ll leave it as is and just get used to it because it has a light first stage (almost a take-up) followed by a nice, clean, very light and predictable break. It makes the Rekord trigger on my HW57 feel heavy. Definitely not a modern lawyer/liability trigger here!

Walther has diagrams of the LG51’s trigger on their website, but I don’t think it’s the same as the LG55’s trigger. The LG55 trigger is shaped different and has more adjustment screws. I’ll need to fiddle around with them to see which one does what, unless someone can point me to the info I need. However, an online search has brought me these drawings that give me a better idea of what’s what.

I’m pretty sure I can figure out which screw does what. The only thing that confuses me here is the far left collar (number 50 in the picture on the right), which has click stops when you adjust it…much like a scope turret. Thanks to the kind souls who posted these pictures on the Yellow Forum a while back!

I was curious about when this rifle was made but couldn’t find any definitive information from Walther online. From what I could find in the forums from others who’ve paid Walther for their serial number lookups (and doing a little SWAG), S/N 086xxx tells me this rifle is 50+ years old. So, it was built back in the days when people took a little more time and pride in their work. A time before time studies and efficiency experts set unrealistic bars for production people to meet. But, I digress. I just like old guns!

I would normally run an accuracy test at this point, but I really need to first fix the compression seal to get the velocity back and stabilized. The accuracy and velocity test will be in Part 2. So far, even though I need to do a little work on it, I’m completely happy with this purchase.
