I had some optic planet bucks and just got a primary arms red dot. I had a larue qd mount already. I used the screw mount for the stock this time (I had just been using the original push to open, for the max11a1 mk2 so
I could take off when going to the pistol format / cfwa bolt ). I think it needed to be more stable for the rifle round
LawBob,
VegasSMG showed me the Velcro trick (use the hook side stuck to the stock adapter) to firm up the push button stock attachment. I prefer not having to monkey with the screw when I swap stocks and this trick tightened things up nicely.

AWWWW NUTS!
REAL MEN DRIVE MIATAS
Since it’s full auto, I suggest a 762 vs a 556. Most are all fa rated anyway but just think the bigger can will breath easier
Lots of good options out there.
Stay away from Ti for full auto. I have a YH phantom Ti for my 300blk for light weight. I like it. But not on this.
Ready for testing the 8" 300 Blackout Max-11A1/15.

The oss says it has stainless baffles. Check the specs not sure exactly which one you have.
If it’s just a Ti suppressor the baffles are Ti also. Like yhm phantom ti
Some theorize that using a brake rather than a flash hider attachment helps bc you get a lot of the initial blast on the brake rather than the can itself.
The asr brake is like 3 mini baffles. But this I got the single port.
Says your 762 is fa rated on 556. Notably not in 762

I think the saker is. You should be fine then. Again, I’d use a brake, but there’s a cost: it’s fucking loud as shit without the cán on.
My hope is the single port asr is not quite as brake-y bc only one port. I liked the shorter length is why.
I had a blast with the 8" Blackout Max-11A1/15 today.I shot 290 rounds. All rounds shot with pistol length barrel and non-adjustable gas block. I had my selector installed but I will use Sam's Eliminator for future testing. The selector was not needed. It was easy to pull singles.
Used Magpul and Lancer poly mags. An aluminum GI mag would not lock-in on a closed bolt.
30-rds 220 grain 15 suppressed and 15 unsuppressed.
60-rds of 150 grain
200 rds of 125 grain
Grains - ROF
125 gr =871
150 gr = 864
220 gr = ? didn't time the 220 but it was slower than the others.
Ejection was in the perfect range. Most cases fell 5-10 ft to the 4-4:30 position.
Surprising finds:
-Easy to pull singles even though the ROF was higher than expected.
- I had 7 light primer strikes. *
*The LPS were tried 3+ times but they would not fire. When I got home the Firing Pin set screw was not tight. I tightened it and will try again. I measured the firing pin protrusion after tightening it and it was .028 so it's now in spec.
Here is what the LPS looked like.
Here is what my 300 BO AR primers look like.
The LPS definitely looks more shallow. I will test next week and see if the problem was a loose Firing Pin Set Screw.

Tubb recoil spring is your friend. I would suggest the one for the AR10 and cut a coil at a time until you are where you want to be.

I'll order another spring to play with.

We have an extra power spring available, if you need extra power to strip a round or increase the ROF.
Make sure you tighten the firing pin set screw as hard as you can with the provided T-handle 1/4” wrench.
