Maccabee Defense SLR information and updates

:confused: it clearly does in the video. I'm really hoping they implement a pin instead of a bolt for takedown.. that's almost a deal breaker for me.

Same. A captive vertices take down pin is totally the way to go unless the design requires it be a bolt to take up excess slack. If the later is the case, these should have a re-design to something that is not bolt or require a tool to take down.

That is one design point ATRS nailed was their single takedown pin and trunion system.
 
I think the biggest problem here is people keep saying "AR15 this" or "AR15 that". While compatible with AR15 parts, and very similar, we still have to face facts that this is a new design firearm.

Ok, to clarify my thought:
When I’m comparing an AR receiver set with this, I’m referring to material type, quantity, machining time/complexity, finishing of the aluminum, etc. I see them as being ballpark similar in cost regarding these attributes. The fact they have spent time, energy to design, develop, test and go through the regulatory hoopla to get them to market, and then to analyze and assess what that market is in numbers and what that market can bear are all metrics that are separate from the ‘more or less knowns’.

Anyhow, last thoughts from me. I wish them luck.

Have been playing with them all day for the past two days. They're machined to much higher standards than AR-15 receivers.

What makes you say that?
 
There is a single takedown bolt. Allen, 4mm head. It is also retained in the lower when unscrewed so you won't lose it!

Works fine for the ATRS DA50 lower. It also has a rear pin like on an AR, but the front Allen head bolt (and the design of the upper fitting into a pocket in the lower) does the lions share of the work.

If the upper slides into the lower snugly and is locked by a bolt, it should be AOK.

I assemble my DA50 and ATRS lower with the bolt almost every day, it takes about 15 seconds. Easy peasy.

Would you rather it had 2 pins instead?
 
If it slides together like a pistol, wouldn't a single pin (like a pistol) be enough? Why the bolt and pin (he said, quizzically)?
No "and pin". There's only a bolt. I'm not going to speculate as to why they opted for a bolt VS. detent VS. another locking method. I didn't design it, I've just had the pleasure of using it and finger banging it for several hours.

Ohhhhhh totally missed that in the photos; I just assumed there was a rear takedown pin and that the bolt served simply to take up slack.

Interesting. I'd guess the decision to opt for a bolt was to further differentiate the design from a conventional AR, perhaps?
 
Put a 4mm allen key in your pistol grip, there you go crisis averted...... Seems like way to much talking down for a NR AR type rifle. Face it if you think $1000 is too much you are A-Cheap or B-Broke. Not sure what magic land you think these types of things come from. Shops cost lots of money to heat, Cnc equipment requires lots of electricty, inserts for tooling cost money, fixtures are time involved (read expensive) to build, journeymen machinists get payed substantially more than mexican or chinese factory workers, even used cnc equipment is in the tens of thousands of dollars, new ones cost more than houses in many parts of the country. How many combos will they sell for all this expense? 100? 500? 1000? Who knows?
A friend of mine just put together a fairly high end build on a rainier arms billet upper and lower, the total bill with him putting it together was $2800 so barring any qc issues with the rifles $3000 really is pretty reasonable. If I could pay $1000 to use my AR as a non restricted I wouldnt think twice about it, so I dont think this upper lower is a bad deal at all. Finally i will be able to practice for 3 gun with my rifle in the back yard ������������
 
Any mil-spec trigger can be installed. Pre-made trigger packs like what Timney makes won't work unfortunately. Also, my experience has been that they're extremely "meh" triggers anyway.

Ah s#!t man. I was really hoping to go with a Trigger Tech and keep as much of this Canadian as possible.
 
Legitimate question: Why? I've been building ARs for years and have never struggled with or felt the need for a drop in pack. Is there some other advantage I'm not aware of other than perceived ease of installation?

Yup. There are advantages to drop in's. There are more and more top quality options for drop in's becoming available all the time. Seems to be the way the industry is evolving. I like to see new manufactures keep up with the times.
Also I love the ease of adjustability with the TT. I can simply turn it heavier for when I want to go hunting and then turn it back lighter for target shooting or ammo/accuracy testing.
For me it's about options and versatility. Not about wanting to take the easy route when installing a trigger

Single vertical bolt will be the production method going forward I believe. But the slide-on-a-frame analogy of a pistol is a good way to visualize it.

Isn't the use of a bolt outdated technology? Only benefit I see is that, when tightened down, it "should" take up any slack and eliminate any play between receiver halves. Not the worst thing in the world but it is a primitive method of accomplishing something.
ATRS accomplished the same thing with the use of 1 take down pin and a spring loaded trunion pin. The design is both modern and simplistic. Actually I'd call it genius. Disassembly is quick and tool less. Receivers have zero play in them.
The whole bolt and wrench thing isn't a deal breaker and it does accomplish what it needs to do but I would have liked to see something a little more creative and current.

So the screw being "retained" in the lower when unscrewed would mean that the screw goes through the lower and sits loose within it. There is no threading for the bolt in the lower?
It would then have to be the upper receiver that has the threading for the bolt to tighten into? Am I correct in my thinking?

Is the threaded portion heli-coiled like the barrel hold down bolt on the Rob Arms rifles? This is a biggie to help prevent the aluminum threads from becoming stripped. I know that the bolt to hold the receiver halves together won't require near as much torque as the Rob Arms barrel retention bolt but I can still see the aluminum threading wearing out over time or possibly stripping due to someone over tightening if it isn't heli-coiled.
Some people have a much higher muscle than brain ratio and I can see this becoming an issue for some if there isn't some reinforcement in the threaded area.
Just my .02c.

I'd have to see the way the upper and lower interface to definitively comment. My initial thinking was it's just a stop pin to block the upper from sliding forward. If so, my idea was a lever actuated pin. Lever sits flush with the front of the mag well when locked. I don't know the actual mating system though. Just thinking out loud.

That being said, this is the initial introduction of the rifle. They built it simple to get a classification. In that case, a simple bolt works. Who knows, maybe needing to tools to disassemble appease the clowns at the RCMP. Down the road, they might change it. I'll reserve major judgement when I see the rifle.
