Initial Review - Sterling Arms International (SAI) R9 Mk1, 9mm PCC

I saw on the Ballistically Speaking video that there now exists an 11" restricted version, any idea when it will hit shelves?

JR said on the slamfire podcast not until there is a change in government and he submits it for FRT.
 
The weakness with 3D printing is not the filament, it is the layer bonding. 3D printed things tend to fail along the layer lines.

Printing long, thin parts also runs the risk of warping.

You cannot produce a single 3D printed stock for less time/effort than you can buy an airsoft unit.
Thank you. Finally someone who knows what they are talking about when it comes to FDM and correctly identify its limitations due to its anisotropic nature.

It's frustrating to see GSG-16 users fall for the scam that is Hardline Tactical. Flimsy printed garbage that breaks and costs 2x versus airsoft MP5 furniture mass-injection molded from Hong Kong.

I've printed and used plenty structural parts that are perfectly servicible on firearms, but a minimalist buttstock isn't one of them. For example, here's a proprietary M-Lok + Arca-railed 10/22 handguard designed to fit and only fit the Grey Birch Fusion barrel nut 10/22 action and the SBI Superlite chassis, and weighs 74 grams when printed with carbon fibre polycarbonate:

I have been printing since 2017. Printed a few useful things in that time. 🤷‍♂️

3D printing cannot beat injection molded parts for cost or strength.

Does that statement extend to 3D Printing with sintered metals? I note an awful lot of suppressor makers now incorporating internal geometry that simply wasn't possible with conventional machining. Those manufacturers like SIG who now print ALL of their suppressors are on the cutting edge. Those 3D-printed suppressors seem to hold up well to high rates of sustained (machinegun) fire without adverse effect. That seems pretty darned sturdy to me.... Surely 3D printed metal parts are superior to MIM parts for both precision and durability?!?

DMLS is good but the machines cost half a million and require an experienced operator. Hence DMLS parts are extremely expensive and the machines are out of reach for the average man.

They've been using 3d sintered metal parts for jet aircraft engine parts for years. So yeah, I'd say sintered suppressors ar GTG.

Been waiting for years for the sintering machines to come down to a DIY pricepoint but alas...

In the user manual it mentions the 10" barrel version of the firearm.

Have yet to see any news about it.
 
in case you missed my TSS review

I modified the width of a trigger tech duty hammer to fit the slot in the bolt, which didn't take much doing.
Then I chopped it down some to match the existing trigger arc height to punch the back of the firing pin.
However, the trigger tech hammer doesn't allow for enough recess in the trigger group as the bolt rides back on recoil.

The Trigger tech is a no-go without them doing a significant revision to their design.
Installed and tested yesterday.
Ran 250rd through it. Used an Sig MCX and machined and polished the hammer to work.
Ran flawless!!
Last pic is after the 250rd.

So this makes me kinda interested.

PCCs need a nice crisp trigger.

Refresh my memory, are these only available with the MP5 style mags which dont drop free? Are they 5 round or 10 round?

Drop free / 10 round / nice trigger makes it useful for PCC competition and that might sway me.

Mags do drop free, there are 10 round mags available, trigger is so-so, at on least the example I have handled.
The trigger mech design is mostly plain jane AR15 , except the hammer is narrow & is shorter/sits lower, which seems to prevent most aftermarket trigger mech options so far.

Someone upthread thread they had used a Sig MCX trigger.

Hitman2, is this 3.5 lb to 5 lb Triggertech Sig MCX trigger the one you used?

That is good to see...although for the cost of a TT MCX trigger at ~ $400 after tax, I'm pretty sure I'll live with the oem one until TT makes a drop-in unit for the R9...and PP wins a majority conservative government.
