Hi guys.
Just got my DT10 back from kolar with my new subgauge tubes and need some help or advice.

I got them home tonight and was practicing the install and removal of my tubes (20 ga if it's relevant) and was really struggling to get them seated all the way...I was eventually successful but chewed the end of my mallet up nicely in the process. #I don't think there's anything wrong with the product but rather I might not understand the required technique. #I feel like the biggest problem is that with the crossbolt locking mechanism of my dt-10 I really don't have a lot of tube rim to strike.

Any words of wisdom or suggestions?

I tried looking online for help and found a video of the install of Briley tubes...it appears they come with a tool that you put in the chambers and pound on to get them in...should I consider ordering these?

Thanks in advance.
 
You could have a big aluminum drift made :S Something like this. You would have to make one for each set of tubes.

Damnit....I didn't read the whole post and drew it up for .410 :S

First, I had to have a small laugh at another poor soul having fit issues with their kolar tubes, you are not the first.

That said, I have owned dt-10's and am familiar with the barrel lugs, I had briley tubes in mine and never had any trouble seating them, despite the lugs and did use any tools.

I would suggest, trying the other gauges and seeing if they are equally difficult or just one set.

If they are all difficult, remove the screw-on choke tube, provided that you paid the extra money for kolar to not apply loctite to your tubes, lol.

Then try inserting them, if the go in easy, the the choke tubes are a little too big.

Are you trying to insert the sub gauge tubes with the 12ga chokes you sent down to kolar? They will have fit the tubes to the chokes in the gun when you sent the barrel. Be sure that you haven't put in different chokes.

Also make sure your barrel and chokes are clean with no plastic debris.

If after all that, the problem will be the chambers are too thick.

Remember that especially the bottom tube, doesn't usually appear to seat completely and that is normal.

You might try some oil on the tubes and chambers to ease installing them, though you shouldn't have to.

The tube should be fairly easy to install. If they are taking a lot of effort that isn't right.

I assume you went through lawry, if after you've tried all the above and are still not happy, best bet is to send them back and prey that kolar actually comes good for once.

If you're problem is that you are lacking accuracy with the mallet and are just striking the lugs, get the tubes in most of the way, but the barrel on the gun and gently close it repeatedly that can help seat the tubes for you, make sure your tube's extractors are pushed in before closing.


Sorry that the above isn't very linear and is a little bit rambly, just typing as I remember. I've owned many tube sets now in the last 14 years, everyone of them was easy to install, kolar and briley alike, and I never needed any more than a plastic hammer.
 
All I've played with is the 20ga. They came back from lawry's with the 20ga tubes installed already, all I did was knock them out and try to put them back in, so it shouldn't be change in choke or dirty barrels/chambers.

I did eventually get them...it just took way too long. I think my best move might be to get those drivers from briley.
 
Yep just hammer them ####s in, you just have to find a good angle to strike them. That plastic hammer they give is going to wind up looking pretty beat so don't worry about taking chips out of it. I find the best way to get them in if they're are being stubborn is to bounce the hammer on them in the same motion you use a stick to roll a snare drum.

Jeepers you're giving me second thoughts about picking up a set of tubes for the 20 Ga Grade IV Citori Skeet I just purchased. I don't like the idea of having to pound on that gun!!
 
sometimes hitting the tube too hard makes them rebound in the chamber and appears that they are not going in when in fact they did go in and just bounced out a bit. I know this from experience. I was putting my tubes in once and didn't think they were going in, hitting them harder didn't do anything, gave them some light taps with the hammer and they went in no problem.
If they were installed when you got the gun back, they would have been just as hard to take out as put in.
make sure you put them in the proper barrel (over in the over/ under in the under) this will make a difference
 
I will try the light "drumroll" taps...it occurs to me that I had to give them some decent whacks to get them out. I am certain I've got the right tube in the right barrel.
 
Get a good bore cleaner. The first time I used one on my Beretta, I couldn't believe all the plastic that just kept coming out.

Try and find out where the tube is catching. Like Gwagen if it is in the chokes, you may be able to rectify that with a less constrictive choke. If it iis in the bore, you may be able to rectify with a good cleaning.

You shouldn't have to beat the crap out of the tube to get it in. I light tapping with the hammer should be all that is required. I have seen tubes that have come from the factory that were simply too big. You will save all kinds of future aggravation to get that problem addressed sooner than later.

I wouldn't be too worried, obviously all of this is done with the barrels separated from the receiver. The worst you could do is maybe scratch your bluing but using the supplied hammer I have yet to damage my Kolar max skeet :)
 
I have resolved the issue. Spoke to Kolar on the phone and he walked me through getting them in. As I suspected the crossbolt locking mechanism is the issue. By turning the knockout around I was able to get them in no problem.
