Pistol Build

As a .30cal guy, I've long wanted a .308 SBR.

After collecting components for a while, I noticed I had just about everything needed to make a cool .308 pistol. So that's what I did this month.

Pistol Build: Spikes Tactical .308 Shorty Pistol

I've been reading recently about some shorty .308s and how with a 12.5" barrel some were getting good muzzle velocity. As a longtime .30-cal guy and a lover of short-barrel guns, I decided to try my hand and see what I could come up with. I'm pretty happy with this build, but as you see it was not without some shortcomings!

Mostly I'm totally enamored of this build, as the components are top-notch and after having function and pressure tested the build, it rocks. That is to say, it meets my standards. Good stuff. However…

So what went wrong?

I love the Aero Precision Atlas rail and find its locking mechanism to be nice...except for the fact that once I put it on for a test fit, I could not get one of the locking lugs out.

The result is that I have a build that lacks a dust cover as I cannot remove the Atlas rail to install the dust cover components. What's more, I cannot adjust the gas block because the rail openings are not advantageously placed for the side-adjustment screw. Awesome. :-| Luckily, the gas is well adjusted as is. But, you know, things change.

I'll eventually take this otherwise excellent build to a more equipped armorer to knock off the rail so that I can install the dust cover. But for now, I'm very happy with the performance of this build. It is CQB zeroed and I look forward to getting it actually zeroed and putting it on a chrono for walking it out to whatever distance it'll be good for.

Oh, and as I didn't have an M-LOK QD sling attachment, I had to improvise with my sling setup. The front is driven with some paracord. It works; for now, but by the time you read this, I'll have a proper QD rail attachment.

A red dot is sufficient for most short-barreled guns, but since this is a .308 I added a Vortex 3X magnifier for those shots that this gun should be able to make without hesitation. We'll see; I may want to put a LPV optic on this puppy. Only training can say! I'll do lots of that.

Join me for training anytime.

I invite you to be my guest (the first time) at the range and throw in with my weekly training any Saturday morning at 8am at Proactive Defense in Northlake, Texas. Whether you're a gun pro, an intermediate-level shooter, or a total newb, we'll work defensive drills at a level you can handle. We're not gonna just "shoot," we're going to train on drills that develop skills we can use to preserve our lives.

Easy Peasy: I'll take care of your range fee.

Just let me know you're coming ahead of time.

Bring your own ammo.

Bring your own gun(s): pistol, rifle...all good.

Bring all the guns you want, but we're only going to train with one. Training requires focus.

One More Thing:

We train whether it's 15°F or 110°F, rain, or shine. If you're daunted by something as insignificant as weather, don't bother touching base. Training is about skills, not feels.

Sorry, didn't mean to stare into your soul.

Anyway, Thanks so much for visiting. I hope y'all enjoyed the content! I also hope you train with your rifle and pistol on a regular basis like a responsible citizen, for these are uncertain times.

Training works.™
