Sneak Peek: SMOS Arms Upper Machined to Match Contours of Geissele Super Modular Rails

Geissele Automatic’s Super Modular Rails (SMR) are popular for good reason. They are excellent rails. Wouldn’t it be nice if there was an upper receiver available to match the contours of the SMR? SMOS Arms thinks so.

They recently gave us a sneak peek of a billet upper they are working on that will have contours designed to blend into the SMRs. Hopefully for SMR fans, this upper received actually makes it to market.

AR-15 Trigger Mount Rushmore

If there was a Mount Rushmore for AR-15 trigger gurus, these two would be on it.

Geissele posted this photo of Bill Geissele and Chip McCormick at SHOT Show. Mr. McCormick is trying one of Geissele’s trigger (hence the trigger finger). This is what you call mutual respect.

Geissele is Gearing Up for a Huge SHOT Show

Geissele Automatics and its related brands are gearing up for a massive SHOT Show. They are rolling out several new products including new rails and triggers. They are also rolling out two new brands under the Geissele Umbrella: NCC and Abraham & Moses Survival Equipment.

You can see a complete preview of all the new products in the video below. The video opens with ALG Defense, then moves on to Geissele’s new products, then details the new coating company NCC, and finally reveals the new knives coming from Abraham & Moses Survival Equipment.

Geissele Super 42 Braided Wire Buffer Spring and Buffer Combo

I have found over the years that it doesn’t really pay to skimp on AR-15 recoil springs. Cheap springs seem to lose length quickly and the use of a premium spring can improve how the AR-15 behaves under recoil. It has also been my experience that most AR-15s will see a marked improvement in cycling and recoil control with the use of a heavier buffer. These are obviously generalities but suffice it to say, a good spring and a heavier buffer can have a great positive effect on an AR-15.


Geissele is now offering a new spring and buffer combo, the Super 42 Braided Wire Buffer Spring and Buffer Combo, that seems to be a fairly solid value compared to other known quality buffers and premium springs on the market.

Here is what they have to say about the combo:

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.

Compared to the stock spring, The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock. The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.

Additionally, you can purchase tungsten weights separately that will allow you to convert the H1 to an H2 or H3 buffer simply by swapping the steel weights with tungsten weights. Most AR-15 buffers have three weights inside the body of the buffer. An H1 buffer has 2 steel weights and 1 tungsten. H2 has 1 steel weight and two tungsten. H3 has 3 tungsten weights.
