AR-15 and AR-10 Build and Customizing Class

Become familiar with the most popular firearms format in the United States, the AR-15 and AR-10. Here is an opportunity to build and customize a rifle. Instruction will include functioning, disassembly of main and subgroups and reassembly, head spacing, troubleshooting and function testing tips, and various cartridges offerings in the AR format. The AR-10 rifles will be covered and the compatibility between the different manufacturers will be discussed.

Students are requested to bring all the parts for a complete build or in various states of assembly for completion during the class, or their own firearms as a whole rifle and bring any parts they may wish to customize. The build and customization of the course will be dependent on what the student brings to class. Students will have the opportunity to use many of the instructor’s tools. Students must be 18 years of age.  All State, Federal and local laws apply.

 Bring safety glasses and your own tools; the instructor will have tools for students to use such as punches, armorer wrenches, vise blocks, disassembly/reassembly tools, and torque wrenches. This enables the student to try the various tools and then they can decide what tools will work best for them before purchasing. Tools will not be for sale at the class.

 If you have purchased a handguard to install on your MSR, please bring the proprietary barrel nut wrench to match.

Class Dates: October 28 – November 1, 2019, time: 12:30 – 8:45pm  This is a five day class.  Cost $250

20 Nosler

Yes, it’s on the way…    How do we know?  Click here. It’s pretty obvious.   Well that and the fact that SAAMI has published the specifications already.  The same print from SAAMI comments that a 32 grain bullet will go 4100 feet per second (fps).

Like the 22 Nosler the 20 is based on the 6.8 SPC case or 30 Remington depending on how you view it.  They both have rebated rims so as to fit in a standard AR-15 Bolt face.

The 20 Nosler will have about eight (8) percent more case capacity by water weight than  the 204 Ruger.  So is the velocity claim of 4100 fps realistic?  On Nosler’s own pages they show the 204 Ruger doing that velocity with the same bullet, so I would say, sure, it just means you will have short barrel life if you load to that level.

It’s long been know that velocities approaching 4000 fps are hard on barrels, the throat is erodes much more quickly regardless of the bullet diameter.  I foresee the barrels for this caliber being chrome washed or Melonite® teated simply to increase barrel life.

The 20 Nosler might have some loading flexibility that the 204 does not in that if you loading for 3500 to 3800 fps there are probably a few more powders that will get there with the larger case capacity.  One thing I noticed in looking for comparisons, the 20 Nosler falls in its own class in terms of case capacity, the 20 BR has just a couple of grains less capacity, but it’s not designed for the AR platform.  The other popular wildcats in this general class either have a fair amount less capacity, or a lot more.  If for no other reason, this cartridge will have a following just based on the case capacity.

There is certainly no doubt, this will be a flat shooting varmint cartridge that will do the job in the dog town or out taking coyotes.22NoslerVs20Nosler

Miller Precision Arms, Guardian, 300 Winchester Magnum AR

Brandon Miller of MPA has been a busy guy.  He has his 300 Win. Mag. on an AR platform ready to offer to the public.  Miller Precision announced this new rifle on July 4th, 2012 in celebration of freedom.  At the time of this writing they are the only company that has a functioning rifle of this type.  Best of all the MPA rifle is an AR, this means not training with a new system.    This rifle is a natural for military use, or what a great way to play the High Power game, F class anyone?

Mossberg MVP Series Rifles

Mossberg claims this is the first bolt action rifle designed to utilize AR style magazines.

Chambered in 5.56mm NATO (.223 Rem) Weaver-style basesCombo package includes a pre-mounted and bore-sighted 4-16x50mm variable riflescope, bi-pod and 10-round magazine 24”, button rifled, medium-bull barrel with a 1:9 rate of twist. and an 11 degree varmint crown finishes the barrel off.  A benchrest style stock with a down turned pistol grip.  The trigger is fully adjustable from 2 to 7 lbs.  A nice touch is the spiral fluted bolt standard from the factory.

These rifles could easily be converted to use any cartridge that will fit in the AR Magazine, most notable, the 6.8 SPC, and the 204 Ruger.   MSRP for the rifle is about $650.  Add $100 for the scope package.

This new rifle is already featured on the Mossberg web site.
