Dlask m4 barrels

Taper pinning is difficult - since one needs a taper bit and a greater level of precision.

KevinB you mean to say they cannot ream the hole to the smaller diameter (by a few thou using a undersize reamer) with a stright reamer then hand ream a taper in the proper final size with a taper reamer ?? :eek:

Well apparently they cant...

I handbuilt a bit stop for my taper bit. It simply wont go further than the bit stop so I can't misdrill it (in theory)

To get a proper lock with a taper pin, the taper should extend the length of the hole. The easiest way to do one or two holes it to either, 1) ream till the tip of the reamer is approaching the far side, blow the crap out and try the pin, the proceed turning 1 rev at a time till you get your fit. (use light even pressure, your hand feel will determine metal removal) or 2) use an over length pin, and trim it to length on a grinder when your done. (method one is the craftsmans way, method two for hurried repairs)

So, has anybody on here had a bad experience,an actual first hand experience,not friend of a friend thing,with the roll pins???

How many people do you need, I've seen over a 1/2 dozen in less than two years not including Ahab's who's we fixed.
 
Shazam: at the time, about 3-4 years ago, their barrels were like this. I cannot comment on the current quality of their barrels. I am sure they must have improved.
The barrel was not marked, so I have no idea what the twist rate is/was, I assume 1/9.

When I owned an AR15 with the Dlask barrel with roll pinned front sight base
I never had any problems, probably most people wont, but it is clearly not the best way to do the job.

It is unfortunate that Dlask is not taking advantage of the current gun market in Canada. They have such potential, being one of only a small number of firearms "manufacturers" of sorts. But they can't seem to get their sh*t together (at least AR15 wise). Imagine the sales if they could make an AR15 that is as close to military M4's or C8's etc as possible.

They will have to redeem themselves before I buy anything from them, and I think this is a common feeling. Now if they would only get on that M203 project, or some other fun project.

Sparrow : and a damn fine job you did of it too! :)

O.K. not meaning to be a jerk or tring to shine you on or anything,but I just got an used upper with a Dlask 11.5 barrel(got it before I talked with you),with the roll pins,short barrel or I would have passed on it.you all know the score on that,right?
Anyways,had my hands on it for 2 days now,just got back from the range,put 60 quick rds though it before last light of the day,no problems,grouped good both 50yds and 100yds,little low and to the right but thats probable me(been 15yrs since I've shouldered a AR(C7)) .
This is my first Black rifle,Bushmaster lower ,RRA M4 type stock and a Armilite bolt and carrier,Yeah,I know ,it's a mutt,But aside from the ugly roll pins on the FSB it seems to work good.
So,what kind of probablems should I keep an eye open for???

I've got a Armalite 16" mid-length upper on the way(someday:rolleyes: ) from Wolverine.the one on it now is just a temp,it was an impulse buy.

Thanks,

Listen dude, if the gun works then it works. Use it, enjoy it I simply cannot live with that kind of work, I want a civvy compliant AR15, not a gun that shares an outward silhouette of one. Joe's work makes you wonder what else he cut corners on or what the condition of the reamer he used was. You should see the blocks of lead he heats up as a barrel vice. What I do know is plinking is one thing, but putting my match fee or course tuition on the line with a Dlask anything is a definite no-go.

Best, Ray
 
how do they stay in business? Ive read many many complaints about thier goods and oddly enough their prices are much higher than other sources.
 
dlask - they prey on the new people and the uninformed....

Hmmmmmm?
Pretty broad statement there HFP75 ...

I've been shooting for over 40 years, so I don't think anyone can call me a "newbie". We could could maybe have some fun debating about whether or not I am "uninformed"?
HOWEVER,
unlike many who chipped in with their comments on this thread, I've actually owned and shot a Dlask 14.5" AR-15 barrel, and a Dlask Mini Moose shorty.
SO,
I think I just have to respond to this thread.

It is interesting reading all this Dlask bashing. It seems there are a lot of people on CGN, with various degrees of credibility, willing to jump in and criticise the very very VERY few folks who are actually ambitious [ = STUPID?] enough to build gun stuff here in Canada, and attempt to make a business and a profit doing so. This goes for the recent Rooster bashing as well.

I was a licensed gunsmith and serious IPSC competitor back in the 80's and 90's. Back then, in the dark ages, before most of you Dlask bashers were even born, there were only a very few smiths who pioneered "practical shooting" here in Canuckland. Joe was one of those pioneers. On the West Coast of Canada, back in the beginning, when IPSC in Canada was just getting started, me and Rod P did the most of the IPSC and military stuff, and Murray C did the PPC/Police stuff. Gunnar was isolated way up in the land of Frozen Tundra. When it came to Canadian practical shooting, on the West Coast, that was just about it folks.

Joe showed up, fresh off the boat, and started working for Rod. He quickly proved that he was then [ and still is] an absolutely fantastic machinest. He was doing better machining than any of us. However, Rod, Murray, Gunnar and I were all serious "practical" competitors as well as gun butchers, so perhaps our philosophy was a bit different. Joe is first and foremost a machinest, and often, an artist in metal. I've always found any work that Joe did personally first class. I've known Joe for over twenty years, and I'd say he has forgotten more about gunsmithing than most of his detractors will ever know. In all that time, he has always treated me better than fair.

If you have problems with his stuff, I suggest you talk to Joe personally ...
 
Having met Joes, I can attest he is first rate. There may have been some barrel issues in the past, but sometimes that happens. I will suggest that Dlask's communication and PR dept is a little lacking though. ;) :D

Taper pins are designed (at least on the AR) to stick out 1-2mm on either side to allow for this...


smart, an engineer who knows how to think must have designed it. Somebody better bronze him, their pretty rare......

Where I generally use them, they have to be fitted for length one way or another, can't have them spinning around sticking out.
 
Just as a note on the taper pin vs. straight pin issue:

Since it takes longer to fit a taper pin than it does a straight pin, it will not be done unless it is determined to be critical, even though it may be desirable.

Think about it this way: Sure there are simple and easy ways to drill and fit tapered pins, but try to standardize those methods - like using a masking tape stop - in a factory. Your parts will be out of spec from one batch to the next. Plus, as an arbitrary example, say it takes one minute to drill and fit a straight pin, and one and a half minutes to drill and fit a tapered pin, that is a 50% increase in your labor cost to produce that part. Added up across the manufacturing process, a 50% increase in costs in any area severly impacts the finished price of your product.

So what seems to be a reasonable thing to an individual craftsman to do, is not neccesarily desireable from a manufacturing standpoint.
