SLR15 Rifles AR-15 / M-16 / M-4 ARMORING COURSE
When: August 8-9, 2016
Where: Owatonna, Minnesota
We conducted a 2-day (16-hour) AR-15 / M-16 / M-4 Armorer Course at the Owatonna Minnesota Police Department. This was our first course here, and we look forward to more. The training room with plenty of table space, decent lighting, and a screen that we were able to project animated graphics of the weapons system, powerpoint detailed pics of gun parts, and especially when looking at finer detail things like machining, stress cracks & wear.
Rifles represented in this course were many, to include SLR15, Colt, Daniel Defense, Bravo Company, Bushmaster, DPMS, Smith & Wesson, Rockriver, HK, Windham Weaponry, and a couple of custom builds.
Day-1 started with going through the course manual that all students are given. Students were supplied with their own set of basic tools that are necessary to do 95% of the work on their rifles (short of restocking and rebarreling, of which wrenches and sometimes fixtures are necessary), Slip2000 "EWL" Extreme Weapons Lubricant and #725 Cleaner Degreaser, etc. A short session of nomenclature was covered, at which time covered every feature and exterior piece of the rifle to include all the hidden design features that most people are not aware of, and everyone prepped the rifles for disassembly work. Everyone was taught the procedure series of checks that we recommend.
Everyone was taught our recommended way to field strip a rifle, and whey we do it this way so as not to cause damage, premature wear or stress on anything. We covered maintenance of where and what to clean, and what needs lubrication to keep it running. We showed why not to use the firing pins as tools. We showed everyone our recommendation of how to remove fouling and why, and everyone got to use our methods.
The entire bolt carrier assembly was covered, to include inspections, maintenance, upgrades, 3 types of gas rings, and differences in finishing and machining. We had several students that gas keys that needed to be staked better, of which we supplied several of the MOACKS tools that were put to good use. Everyone was introduced to the different types of gas rings. We went through what each types does, and their proper installation order.
After lunch we covered the lower receiver assembly. Everyone had collapsible stocks, and we showed the proper mounting & gauging, and made sure everything was properly staked. The lower receivers were disassembled. We went through the fire control group, to include detailed inspections of all the sear engagement surfaces, spring types, single stage, and two stage trigger systems. The end of the day was spent with going through in great detail the eight cycles of fire, proper timing, .223 vs 5.56, different gas systems, etc
Day-2 started with a review of everyone that was covered on day-1, with some greater details and myths covered. We then got into a session on the timing as it pertains to proper cycling, and showed what effects timing, and how & what happens when it is out or proper time, dwell time, suppressor issues, etc.
Everyone then stripped their lower receivers for a further inspections and troubleshooting session. We showed examples of good & bad machining on parts, and how this effects the entire rifle. Once factory machining was covered, we then showed where people alter trigger systems by doing a trigger job, both good and bad, and covered whey we don’t recommend that people do a trigger job on a work rifle. Lastly we went through full-auto, burst, and illegal street conversions. Once everyone was comfortable with the entire lower receiver assembly, the were put back together, inspected, and made sure everything is in proper working order.
The last half of day-2 was spent on the upper receiver assembly. There were two piston systems in this class, so we showed in great detail how these work, and covered troubleshooting and stress on these. We covered barrel removal, mounting, gauging & inspections. Everyone was allowed to rebarrel their rifles or make adjustments. Everything was gauged, and we had several rifles and were improperly mounted. This improper mounting was causing premature wear & stress, of which these rifles were fixed before they left the class. When inspecting barrels that had been removed, none of them had been put together to the Milspec from the manufacturer. Every barrel that was pulled, was remounted to Milspec, torqued, and properly indexed. Once all the rifles were put back together, everything was inspected and gauged to make sure it was in proper working order. Everyone did chamber inspections, checked & gauged the four gas seals, firing pin protrusion, trigger press, and headspace.
Here is a brief overview of a few things that were covered:
History of the Weapon
Cycles of Function
General Disassembly & Assembly
Identification of Common Problems and Parts
Nomenclature
Identification of Group Components
Semi, Burst, and Full Auto Parts and Conversions
Complete Armoring Disassembly / Assembly
Barrel Replacement
Cleaning and Maintenance
Sight and Distance Considerations
Ballistic Issues
Barrel: Twist, Length, and Profiles
Gas System
Parts Interchangability, including Brands
Headspace
Firing Pin Protrusion
Trigger Jobs
Chamber Inspection and Issues
Troubleshooting, diagnosis & repair
Gauging, Inspections, Stress & Interval Issues
Accessories and Customizing
Tool Options and Selection
Iron Sights
Optics
SOP/MOD Accessories and Additions
