Anyone seen these yet? Looks promising, little pricey but similar to the Hahn but easier to install and it takes Glock mags.
Military Arms Channel just released a video on it.

This has my interest.  I wish I wouldn't of ordered a Colt adapter last week..

Anyone still have Glock mags on sale?

I'll probably buy one of their complete uppers with the mag well adapter. I've been looking for a Glock compatible 9mm ar15 for a long time and this seems to have all the features without the fuss. Definitely looks like a winner.

It even has a mini feed ramp.  The angle of the Glock mag obviously leaves little to work with there, but is that the first Glock setup with a ramp?

The mag release on the bottom would take some getting used to...

I like it.

I wonder how many times I would dump the whole thing on the ground with the AR mag button before I got used to the mag release

ETA looks like they thought of that and have a wedge spring of some sort in the front to keep it from dropping free

If it works well, it looks like an interesting option for those that prefer blocks.

Let's see who the first place is to 'copy' the design and sell them for ~$100...

Yes it will. This product has been needed for some time.

I've got a dedicated Glock lower but it would be interesting to compare the LRBHO reliability in this device.

You could always use a "bullet button" when using the block.  Then no risk of dropping it.  @RDTCU

That mag release is absolutely genius in its simplicity.  I'm kind of surprised no one else thought of it earlier.

The mag block extends below the magwell of the lower, unlike most mag blocks, so you have all kinds of real estate.

I'm aware.  There have been other attempts at Glock mag adapters that extended below as well, yet they all had gimmicky mag releases that required mods to either the gun or the mag.

I know it comes with a tension screw, but if you are really worried you can install it with a bullet button.

I think the tension screw is the green dot peeking out of the magwell flange, so you can take any wiggle out of the adapter without making it hard to remove.

I have a bunch of Colt 9mm mags and Glock mags so this would be nice for my M-16.

So if you have your Colt bolt modified to work with this unit, can you continue to use your Colt bolt in a Colt 9mm, or does the mod render it only useable in the Glock mode?

A bolt ramped to accept Glock mags still works with Colt.  You won't have any issues.

Yep, my JP Enterprises bolt will work with both mag types.

Wonder if the stock AR magwell has enough room for an adapter like this and large frame(.45acp & 10mm) mags

He says at the end of the video they are working on "other" mag brand blocks. I wonder if they are working on like S&W mags or maybe sten or some other cheap mags.

Hahn has had STEN magblocks for years now.  Works w/ the Olympic upper.

Very good video. This looks like a pretty nice product.

I have used colt style mag blocks before with very good results, but this looks like a great option for a glock shooter. My 9mm ARs have become my go-to range guns. All are reliable, accurate, cheap to shoot, and have less uncomfortable blast than a 5.56.

I made it to a range with a 12" steel gong at 200 yards. With a Weaver 1-3x scope, sighted in for 50 yards, putting the point of the reticle where it transitioned from thick to thin (I forget what this area is called) was pretty much on for elevation, and we were able to ring the 200 yard target most of the time with a simple rest. Pretty neat to ring steel at 200 yards with a 9mm and $8 per box of ammo (wolf steel cased, box of 50).

I read elsewhere that at that range, the 9mm projectile might only have a bit over 200 ft/lbs of energy, but it was still good fun. At 50 yards and less, shooting the larger steel targets for handguns was actually too easy.

I e-mailed with Team Stern yesterday. I asked if they were shipping ASAP.....This was their instant response:

"Our shipping policy is to ship within 3-7 days. Our internal goal is to ship same business day. However, we have re-engineered the mag release to be flush with the mag well so it cannot be hit or caught on anything. Also, we have upgraded the material to 4140 alloy steel which has a very high yield and tensil strength. We have been holding orders for a couple days longer so we can get our improved mag release added.  We are hoping to have this completed by Wednesday or Thursday."

Was a great person to email with and was lightening fast.

I am pretty sure I will be ordering one.

It's steel now?  That's significantly less appealing.  (I swear I remember reading that it was aluminum, originally.)  I wonder if they're fixing problems in early testing or trying to stick at the goal price point with cheaper materials?
Link Posted: 12/5/2017 9:56:17 PM EDT
[#44]
I think they meant they changed the material for the mag catch.
Link Posted: 12/5/2017 10:06:48 PM EDT

Stern verified that just the mag catch release is being changed to the new steel.

Saw a video of this a last night and immediately thought of his adapter and wondered what had become of it.

Ah, that's better, thanks for checking and clarifying.  With how long of a lever that is, I could see how aluminum might be too flexy.
