Mine functions with the 35 degree with unsuppressed 115 and suppressed weak stuff like Syntech 150.

I run mine 100% suppressed, but run 124gr, 147gr, and 158gr rounds. Would the 35⁰ or 40⁰ block be better? I keep it loaded with HST 124gr+P's for HD but dont shoot them at the range.

Mine ran like a champ suppressed with the 40*. Still waiting for the 35* to come back in stock.

Looks like the little stribog is gaining popularity. Lots of parts and guns out of stock on global ordnance. Still on the hunt for a 35* locking block and Lingle lower.

I found a used mini-bog at a decent price and grabbed it.  Seems it was pieced together from 2 different guns as upper is FDE and lower is black.  Got to shoot it today with an Omega 9k and a spare PA red dot I had sitting around.  Need to find a different sight for it, but I like the gun so far.  The bolt release could use some improvement.

They make a bolt release with a larger and longer finger ledge. HBI makes it.

Hey guys just wondering if anyone has replaced there tailhook with This. after they got approved there form 1 back? I like the look and easy to put the tailhook back on if you have any reason too.

Changed my setup a bit. Finding a sling QD for the brace was a PITA. I'd like to really put a pressure pad but the Bog is short half a MLOK slot. What does everyone else do?

If you're looking for a Lingle lower, they are or were in stock just a minute ago.

Got my form 1 back. So now I just need to go and shoot it. I use Silencer Shop kiosk to do the form one. It took one month almost to the day to get the stamp approved.

You want the HB short stroke buffer for sure. I changed the trigger springs as well. I eventually ended up swapping the stock lower for a Lingle scorpion pattern lower because I was having feeding issues and didn't like the mags. I think the lowers are definitely worth it, but expensive.

Plus you can get the 40* locking block from Global Ordnance and the 35* are set to come back in stock in the next couple weeks. Makes the delayed system open just a little bit slower to reduce recoil.

What are the differences between the 35* and the 40* block ?
8/25/2026 10:15:55 AM EDT

why was there a parts upgrade from the 40* to the 45* if people are just going back to the 40* ?

As I understand it, the switch to 45 was thought to help with reliability problems with early Stribog with certain ammo.  In the end, the problems seemed to be more due to the magazines than the locking block angle.  The lower angle blocks delay the opening more which reduces recoil and help counteract increased backpressure when adding a suppressor.  The downside is that the increased delay may cause issues with some underpowered ammo, but the advantages outweigh the disadvantages for most people.

ahh okay, interesting! I appreciate the insight.

I will be running a suppressor eventually - so go with lower angle block ?

I honestly don’t think there is any good reason to keep running the factory 45 block nowadays.  Whether the 40 or 35 works better probably depends a little on what ammo and suppressor you run.

I cut my A1 barrel down to 6" and put a 3 lug adapter on it and run a GSL Fatman.  I got this before there were A3s and did the "Free" ATF form.  I like the wire stock, it sits lower that the Safety Harbor one for an easier co witnessed sight alignment for the red dot and flip up sights.  The straight mags run great and seem to fit the vibe.  I didn't care for the Lingle lower and PSA mags.

Thanks!  This one is a 20rd mag.  Makes it a great size to shove in a backpack.  With a short stroke buffer, I haven't had any issues with the straight mags.

Grand Power made it, it was the original Stribog stock.  I'm not sure if they still make them, I don't think they were popular.  I got it used.

Yes you should be fine.  I did the same (3-lug with R9) under a JTAC 3.25" handguard.  I prefer it to direct thread as it's easier to pop on/off, especially if you plan to use the R9 on other 3-lug mounted hosts.

The thing that matters is whether the suppressor fits under the extended handguard, not whether it’s direct thread or 3 lug.  The R9 is 1.56” in diameter.  I’m not sure I’ve seen a 3.5” Stribog extension from KDG.  The older ones were 3” and the current ones are 3.25”.  The current ones have an ID of 1.7”, so a R9 should be fine.

If you are talking about the 40* locking block? Global Ordnance has them for sale at $55. 35* blocks should be showing up in the next couple years. Guy on reddit says he will make 30* or 25* if there is enough interest. Europe has a 30* locking block but no idea when or if it makes it to the states.

I suspect he’s talking about the charging block, the block that the charging handle goes into, not the locking block with various degree angles that the roller pin goes under.  HBI makes a locking charging block that has a ball detent that locks the charging block into the front m-Lok slot so it doesn’t move around under recoil.

this is correct, i read the OEM charging block is some sort of polymer?  

HBI said their charging block doesnt fit the A3-S model as it sticks out the from of the gun, but if i get an extended hand guard, i dont think it would be an issue?

I was the 1st one to make one and still the only one that has one. I had offered them for a little while.  I got a lot of "Take my money!", but no real interest mostly because because of the receiver work that need to be done, so i remain the only one that owns a couple of them. I had even made dual folding charging handles designed specifically for them.
