New Enhanced 9mm magwell block, The ST-EMB.

The ST-EMB's 1pc. Design is Reliable, Adjustable, and Affordable. No other magwell block on the market can compare. 

The ST-EMB offers the same Advantages found in a Dedicated 9mm lower Without all of the Dis-advantages that come with it!

Why Limit yourself to a single caliber and be stuck with no adjustability when your rifle is not cycling properly?

The ST-EMB is Compatible with the following 9mm magazines:

-Spike's Tactical/Metalform 


-Modified Uzi



-Beta-C drums 



-Bottom loading design.

-Patent Pending triple tension pin system to insure the block will NOT move or fall out even under the harshest environments. Its like having a Dedicated 9mm lower with no loss of adjustability!

-No Gunsmithing required.

-No permanent modifications to the firearm are required!

-Uses standard AR-15 bolt catch.

-Simple 5 minute installation and Removal, Great for the guys that want to switch calibers often.


-The ST-EMB offers adjustability Not found in any other system.

-The biggest flaw with the 9mm platform is not having the adjustability to work with a wide variety of aftermarket parts, magazines, and ammo. A simple adjustment to the ST-EMB can turn your single shot 9mm AR into a 100% Reliable Semi-Auto!

-The ST-EMB features an extra wide mag catch slot that allows the user to adjust the magwell block up and down so the feed ramp can be positioned perfectly every time.

-With our New Patent Pending Adjustable ejector you now have the ability to adjust the ejector up and down so it can be positioned with the bolt perfectly every time. No more dragging on the bottom side of the bolt causing excessive wear, No more weak ejection, Perfect ejection every time. The adjustment screw also keeps the ejector nice and tight, wobble free.


-The body of the ST-EMB is CNC machined from 6061 Aircraft grade aluminum, all steel parts are CNC machined from 4140 Chromoly and properly heat treated.


-All of the aluminum parts have a Black Mil-Spec Type III hardcoat anodized finish and all of the steel parts have a Mil-Spec Phosphate finish.

-Each block is then finished off with the Spike's logo.

100% Made in the USA and backed by our LIFETIME Warranty!

Please Note:

*The ST-EMB does feature a Last round hold open but the Magazine also needs the provision for it to function.

*The ST-EMB is NOT designed for use in an Olympic Arms system.

*We recommend installing the block flush with the top of your receiver, we found that its a good starting point to work from.

*All ejectors come pre-set to Factory height so adjustment may not be required.

*The ST-EMB requires 3 SAE allen keys (Not included), 2 for installation and 1 to adjust the ejector. 


3) INCLUDES 32 round 9mm C-Products Magazine 5-Pack ($99.95 Value)

Outstanding quality, best functioning 9mm magazines on the market. 

9mm Mag Details:

- High quality stainless steel robotically welded 

- Straight feed lips with orange follower

- Corrosion resistant Black finish

- Provisions for round count at the 10, 20 and 32 round spots. 


4) Spike's Tactical ST-T2 Heavy buffer and ST-9BS combo ($41.95 Value)

While our Stainless Steel/Tungsten buffer is one of the BEST buffers on the market they can sometimes be overkill in some applications and they are an expensive jump from a Carbine buffer.

We wanted to fill the gap between a Standard Carbine buffer and our ST-SST Stainless/Tungsten buffer.

We came up with something that offers the HIGHEST performance at a reasonable price.

This buffer is one of the softest shooting, smoothest and quietest buffers on the market not to mention it looks awesome. It doesn't have any weights to move around or fluids to leak out, it's 100% maintenance free!

It weighs in at 4.3oz. which is actually .2oz. heavier than an H2 buffer (4.1oz.).

It's CNC machined from Solid Billet Aluminum Bar Stock, Not Casted then Machined like all the Yellowish/Goldish buffers on the Market.

It's Anodized Matte Black and Laser engraved with our Logo.

So you're probably wondering what's inside to make this thing so great and different?

Each buffer is filled with HDTP "High Density Tungsten Powder" so there is No reciprocating weights inside to make any noise. It also makes for a Very Smooth cycling rifle.  It eliminates the chance of bolt bounce and muzzle rise in full-auto. It also cuts down on Felt Recoil.  It's a HUGE upgrade from a Standard Carbine buffer!  It's designed for .223/5.56 but it works in all Calibers!

After its filled with HDTP it's topped off with a mil spec bumper!

Here are some weights I came up with to compare to. These weights may vary from mfg. to mfg. or from one scale to another.

Standard CMT carbine buffer - 2.9 oz.

CMT H buffer - 3.8 oz.

CMT H2 buffer - 4.1 oz.

ST-T2 - 4.3oz.

ST-9BS - 9mm buffer spacer.

****The ST-T2 / ST-9BS combo is perfect for 9mm applications****
