Time To Shoot

 

So what kind of LSP are you, and by the way we doubt that's your real name, if you don't even shoot? Good question, punters. To set the record straight I headed for the range this morning.

There it was, hot as an oven under the Texan sky, and I was on a mission. Viz. Zero in a new and specially crafted AR15. But at what range? There's plenty of pros and cons to the 25, 36, 50 and 100 yard zero, and beyond, but I went for 36 because that's where the shooting bench had been moved respective to the nearest available target. 

 

After a quick bore sight, the weapon was on paper in the 9 ring and I dialed up twice to hit the X on the third shot. Awesome, rifle and optic worked, except that wasn't quite true. Sure, the gun was on but it wasn't cycling. Why? Because the cunning armorer who'd put the beast together hadn't installed its gas block correctly, it wasn't aligned with the barrel's gas port, turning the DAR (Deadly Assault Rifle) into a one shot wonder.

Huh. After a few shots on a steel turkey I moved over to .22 plinking with a Ruger American. A heavy metal bird took a beating along with a small spinner, and then it was time to head for home and a serious meeting with Block, Tube, Pin, Barrel & Co.

You see, the builder of this gun somehow forgot, perhaps he was distracted, that he was working with a 16" barrel. He thought he was assembling an 18" setup and labored accordingly. This meant the gas tube was too long and when fitted to its block didn't align with the barrel's gas port. No hot gas working that famous impingement system, you see, and thus no BCG cycle. What to do?

Utterly Wrong

Stare in slack-jawed, NRA consternation at the offending article and the sheer, brazen, literal incompetence of it all? Take it to a shop and ask them to fix it? Or do it yourself. I chose the latter route. It's not hard. Remove the hand guard, tap out the gas tube's retaining pin with a cleverly small hammer and roll pin punch, then loosen the gas block, slide it forward to the awesome Surefire SOCOM muzzle brake, which demands a suppressor, and remove the gas tube.

Right? Let's See

Well done, you're nearly there. Next step, produce a gas tube for a 16" barrel, clean it, mine was dirty, and press the tube into the gas block. Make sure the retaining pin holes on tube and block align, then tap the retaining pin back in. Replace hand guard. Done.

At least that's the hope. It looks right, but I'll test the offending article out tomorrow on another range at a church shoot. It'd better work or there'll be trouble, and then some.

Deadly Assault Rifle Hi-Jinx

Because I'm a patriot, I have an AR15. It's made by CMMG and I've had several years of shooting fun with the little gas-driven blaster. But I wanted to change it up; swap out the stock handguards with a free-float tube, install a gas block, and a single point sling mount. 

Go On, Take Your Gun Apart

Off went the flash hider, the barrel nut and the front sight gas block. Fine, but the gas tube roll pin didn't want to come out. It did in the end and the new one, that came with the new gas block, didn't want to fit in it's allotted hole. After a lot of aggro, I filed it down slightly and drove it home.

The Old D Ring

The new barrel nut went on easily enough, along with its Yankee Hill handguard, and the sling mount was simple to install. I'm pleased with the end result, but there was an adventure half way through the project.

Oh No, We Can't Sell You That!

Looking down at my old, dirty, gas tube, I thought why not get a shiny new one? So I drove to Ray's and asked for one.

"Do you sell carbine length gas tubes?"

"Oh no, we don't have any."

"But what's that, there, in a plastic bag? Look you have about five of them."

"Hunh! We do!"

"Well that's great, I'll buy one."

"I'm sorry, you can't."

"Excuse me?"

"No. You can't buy those."

"And why not?"

"You can only buy one if we install it for you."

"Of course. And how much would that cost?"

"I don't know, sorry."

"Goodbye."

I felt, for a moment, there in the gunsmith's section of Ray's, that the world had gone completely mad. 

Looks Good, Does It Work?

As soon as it stops raining and snowing, I'll take the gun out to the range and see how it shoots. The free float tube should improve accuracy, we'll see.

Shoot straight,

LSP
