Fellow gunnutz;
With apologies to you all in that I'd meant to have some range time done by now, I'll begin the thread on the latest test vehicle that's wandered into the safe.

As some here might know, I had just finished putting together a bit of an old school Lakefield Mossberg 500AB bear repellent piece for our eldest daughter during which time I became familiar with the products from S&J Hardware.

In short order I'd installed 3 of their Hi-Viz, no bind followers and 2 of the HD magazine springs and was in the process of ordering another couple followers when I saw they had last year's AS-40's on sale.....

As I'd been reading and researching the various Turkish made shotguns for some time, I thought I'd take the plunge for the sake of science if nothing else, so one was quickly shipped across country via Canada Post.

My initial impression is that they are very well machined and finished - much less rough than the Baikal or Boito shotguns I've owned in the past and truly in my opinion slightly smoother than a new economy 870 or Mossberg 500.

The trigger is a bit thin for my taste and I can measure the pull if anyone is interested, but it's quite light, very crisp and certainly manageable.

As the shotgun came with a Hi-Viz, no bind follower, that got installed forthwith.

They used a good dollop of thread locker on the one I got, so I strip the rest of the parts out, put the receiver into a padded vice, push the follower all the way to the front of the magazine with a metal rod and then heat the magazine tube up to a target temp of 375°F as that's when most thread locker/epoxy gives up the ghost.

Note the hockey tape for extra grip on the mag tube and the Canadian Tire Boa Strap wrench - which worked slicker than snot on a doorknob.

They use a finer thread than a Mossberg on the mag tube, so a lot of turning to the left removes it. They also use a MIGHTY magazine spring in it - all of 27" long and quite HD compared to an 870 or Mossberg, so when it comes out, be prepared for the stock follower to go airborne. ;)

The stock follower that Uzkon uses is plastic, but thinner than I'd be comfortable with somehow and since I've now been fully indoctrinated in the Hi-Viz, well nothing else will quite do...:)

All apart with parts to go in.

I chose the Type 2 I think it was - as it feels similar to the Mossberg model in my existing tenting gun, so I wanted to keep as much the same as possible - even though the slide release and safety are different than I'm used to.

Again not that it needed the Hi-Viz follower installed to run better, it now will run 4 shells out as fast as this semi-old guy can pump the action.

Here's a shot of it compared to the tenting gun we've used for 30 plus years.

It is similar to a 870 in that when the action is all the way forward the shell lifter is in the down position and it's a bit of a finger pincher when loading it - compared to the Mossberg system. It's not a deal breaker, just different.

When I get time to slide up the hill I'll try to run both some speed drills and some patterning tests with it using buckshot - just to use it up as I don't carry buckshot inside shotguns anymore and haven't for years. Again that's a personal preference and I'm not trying to start a bladder pressure contest or make converts.

Thanks for looking and all the best to you all this spring.

Great report. I have the AS-41 and I'm thinking of doing this mod.What did you use to heat the tube?What do you think of the placement of the slide release on the Uzkons?I find mine pretty awkward to use.

Good morning to you sir, I hope this soggy Saturday morning finds you doing acceptably well.

Thanks for the feedback on the report, as stated it's more of a cursory overview at present as no shooting has taken place as yet - and the present rain while certainly helpful for reducing the length of our forest fire season won't encourage me to shoot the thing today either.

I use a propane torch with a fine tip to gently heat the magazine tubes, but one has to be really, really careful with an open flame as the temperature is around 3600°F when wound out - so it's way, way overkill and one absolutely can damage the finish on the magazine tube, the receiver finish and for that matter damage the metal components.

A typical heat gun will attain temperatures above 1400°F actually so even there we need to pay close attention or we can damage components to the point where we'll be replacing parts.

As stated the target temperature for making most epoxy or thread locker go away is only 375°, so certainly hotter than most folks can grab on to - well some of us who have welded too much, spent too many hours with a grinder or have injured fingers don't apply here - but anyway its not that hot really.

In another thread I read of folks using the stove element - electric stove I'm thinking - and I could see that working maybe - but after 34 years of marriage I know how welcome most of my gun modification projects are in the kitchen - even if it's my good wife's arm I'm working on!;)

The hockey tape was the key to getting the strap wrench to grip on the mag tube and one wants the wrench as physically close to the threaded section as possible for the best mechanical advantage AND least possibility of twisting or bending the tube. Whatever heat source one uses, its nice to have one which allows a small area to be heated to get that all taking place correctly.

On the issue of the slide release I'd say they could have made the release tab another 1/8" longer and it would help a bit, but to me it's controls are reasonably close to how an 870 runs overall.

The old Lakefield 500AB in the photo has accompanied me all over 3 provinces since I was 12, so 42 years now if my math is correct and any variance from where the controls are on one most certainly seem a tad foreign as far as muscle memory goes. I'll add that shotgun has taught me not to fear a plastic trigger guard and trigger component housing, since it's been a passenger in many tractors, pickups and back pack trips. :)

That said and I'm sure this is heresy for the many adherents to the church of Ithaca, but I much prefer how the Uzkon runs overall compared to any 37 I've handled and/or shot - personal preference of course - but there you have it.

Again I hope that made some sense and was helpful for you or someone out there in the ether space. Good luck with your shotgun whichever way you proceed.

Fellow gunnutz, prospective Uzkon buyers and the rest;
Good morning to you all, I trust this finds you all well on this second last Sunday of March - already!!!

We finished the yard chores in sufficient time for me to roll up the mountain behind the house a couple thousand feet and do a wee bit of shooting with the AS-40.

Range conditions;

The road in was a tad entertaining, but Dodge managed to stay on the skid haul road despite the snow, so here's the gear lined up for testing. I'll note that the fast twist .223 Ruger American travels everywhere with me in the hills if it's wolf or coyote season - which it still is here.

Biodegradable targets all set up ready for test runs.

Someone else had been through the range during the winter, I hope they're still out there and evaded the wolf pack that's moved into the neighborhood.

I shot a good handful of plain old AA 1oz trap loads initially and the Uzkon feeds and fires them as fast as this old, cold guy could run it. Not even a hint of a malfunction which is gratifying to say the least.

Then we moved to a pattern board and fired a 3" No 1 Buck at 12 short guy's steps from the board. The aim point is the left dot.

This model has no replaceable chokes - it's Cylinder bored and really as mentioned I'm more than okay with that as it's going to eat slugs for most of it's life at our house. I will note that the pattern is about what I've remembered and expected from other short barreled open choke shotguns. One can definitely see how they earned the nickname "Alley Broom" anyway.

Lastly I ran some home loaded Lyman Foster type slugs into the Larch bark targets and finally for the photo I shot a single Score 1 1/8oz slug at the right dot of the target board - again at 12 of my 5'5" steps so not quite a meter I'd suspect.

Overall my impression is still very favorable - certainly enough so that it's not been transferred into the trading section of the safe.

A few points come to mind that I'll share if that's okay and again it's just my impressions.

It's much livelier to shoot than the Lakefield 500AB and noticeably louder too. So I'd not say it's a great "starter" shotgun for beginning shooters as it might turn them off of our grand pastime. I run glasses, plugs AND good muffs when I do range work and I'd most certainly recommend that shooting hot loads from a 14" barrel.

It would certainly be a candidate for a Decelerator and even though they have a unique shape to the existing recoil pad, I do believe I'm going to figure out a way to graft a Decelerator onto that machine.

Lastly if I can find a suitable donor in the parts bins or at the next Penticton gun show, I'll install a trigger shoe and see if my trigger finger gets along a bit better with it than the stock trigger. Full disclosure here is that unless it's a double action revolver at our house, it's either equipped from the factory with a fairly wide trigger or has a shoe installed - it's a thing some of us old timers do sometimes it seems.

Anyway that's the initial range report on the little shotgun. If there's any interest I can snap a couple photos of the Decelerator install whenever chores allow for that work to be completed.

All the best to all my fellow short shotgun enthusiasts out there.
