The long action Outlaw is a 500fpe .458 caliber hunting rifle.
Thereís no magic or
secrets involved in making a powerful airgun, itís just simple physics, the
rifle has to flow more air. The
energy source is compressed air and you have to use a lot of it to make a higher
power airgun. To
flow more air you need a bigger valve and a heavier hammer and a stronger spring
to open the valve against increased resistance.
But when making things bigger, you have to make sure that youíre
thinking of the shooter and the proportions necessary to make it feel right to
the shooter, otherwise you end up with an oversized, clunky rifle.
The solution is to optimize air flow using finesse instead of force to
make a usable hunting rifle. With a
25Ē barrel, this rifle is 44Ē overall.
It weighs approximately 8lbs. 6oz. The
stock is familiar to tens of millions of shooters because the stock is the same
shape and proportion of modern center fire rifles, like the Winchester model 70
and the Remington 700.
The LA Outlaw shoots a 430gr bullet at 732fps, which is 509fpe. This rifle will produce two powerful shots from its reservoir on one fill. It doesnít need to be line fed from a scuba bottle, it doesnít have the dependency of life support from a remote air source.
The .458 cal. barrel is
made expressly for airgun use. It
is not a firearm barrel. This
barrel has the correct rifling configuration and twist rate for an airgun.
I chose .458 cal. for this rifle so the shooter could use any of the
ready-made bullets or bullet molds intended for use for the 45/70 cartridge.
Because the barrels are made from solid bar stock they are machined to
the exact bore size without exception. This
way the standard size bullets fit the barrel; it is not some oddball caliber.
The Outlaw rifle is tremendously adaptable. I shortened up the Outlaw rifle and made a pistol. Now Iíve stretched the Outlaw to make a 500fpe rifle. During testing the rifle exceeded 600fpe, so I had to make the valve a little smaller because my target was 500fpe. When building an airgun a balance must be struck between size, weight and power. This describes how the gun can be used and the number of shots per fill. Iím not after ultimate power, all of the rifles and pistols Iíve made have been capable of higher performance, but what good is ultimate power if the gun canít be carried or used readily? I have certain energy levels as a mark that are ideal for the purpose.
The LA Outlaw rifle operates on high pressure air, 3,000 psi. It can be filled from a scuba tank, airgun hand pump, or high pressure (3,000 psi) compressor.

Checkered add $85. (checkering can be done on all grades except Stalker.)
I set out to build a "Standard" grade rifle. When I find a stock that has a blemish or needs a repair this
serviceable stock is discounted and it becomes a "Stalker" grade rifle. The stock may be very good
looking, and you may not even see the repair, but it is repaired and I can't sell it for the Standard
Most of the stocks I make are Standard grade. It is becoming more difficult to purchase higher grade
wood at an affordable price, but if I have a higher grade stock, I will offer it.
I make a limited amount of higher grade guns, but the grading is done after the stock is finished
and the metal is polished & blued. Although I may pay more for higher quality stock blanks, not every
one of those blanks will make a truly fine stock. And some metal, no matter how hard you try, will not
polish to a fine enough finish.
Not every gun intended to be a higher grade will result as an acceptable finish, one that will be
considered a higher grade.
I don't take deposits or any money up front. I only accept payment when
your rifle is finished and ready
to be delivered.
The standard rifle I make is right handed. I can make left handed rifles, (putting the machine cuts on left side or the right side is the same amount of work, so I don't charge extra for it) but you just need to tell me at the time of ordering so I can machine the parts for left hand. It has a genuine left hand stock too (a mirror image of the right hand stock). See the Stocks page.
