Before You Buy A M4 or AR-15 Know Your Facts

Before you buy one of the many M4 variants, I suggest a little time spent researching different companies makes and variances. Refer to the video I made a while ago for some information. Also, there are many links within the video description for follow up.

Many companies selling M4 and AR variants today try to sell a carbine or rifle that may be suitable for plinking cans, shooting gophers and an occasional range outing, however will not hold up to the standards required for hard use and long life with a high round count. Few companies meet the criteria lined out in the TDP of which Colt and FN abide. Bravo CompanyDaniel Defense, LMT, and Noveske are some of the very few companies producing carbines and rifles that meet or exceed these standards.

Companies that have been proven to not meet this standard of critical criteria are DPMS, Rock River, Bushmaster and Olympic Arms. Now before you freak out, they do work for what most people use them for. The fact is, they do not have many if not any of the criteria outlined here and in the video I presented.

Some of the TDP contains: Auto BCG (bolt carrier group), 8620 BC (bolt carrier), Shrouded Firing Pin, Parkerized Exterior, Chrome lined, USGI specs, Mil-spec gas key hardened/heat treated and chrome lined, secure gas key with "grade 8" fasteners properly staked, Carpenter #158 Bolt, tool steel extractor with black insert, Shot peened, MPI(100%), HPT (100%), 4-coil or 5 coil spring, 11595E Certified Barrel Steel, 5.56mm Chamber NOT .223, 1/7 twist Barrel, M4 Feed Ramps, "F" Stamped FSB, Taper Pins, 7000 series lower receiver, Mil-spec diameter buffer tube, properly staked castle nut, Properly marked and weighted buffer, "H" "H2" etc. Also included is properly gassed systems with proper gas port size tube diameter and length. Mil-spec RE (recoil extension).  There are other facets not mentioned here however these are the biggies.

What I had to address with some individuals: Bushmaster has refused to release any information or certifications regarding materials, specs, etc. Bushmaster does not hold the TDP or design schematics for the M4, but is assumed by many to reverse engineer after measuring Colt parts (as many do). Every Bushmaster I have handled, owned, seen, or sold, has lacked a STAKED castle nut. Bushmaster does NOT have an "F" marked FSB, or an H buffer. Barrels that have been tested by individuals, has shown they are NOT 11595E.  Your barrel is 1/9 NOT 1/7 and made of who knows what materials exactly. All MPI and HP of Bushmaster is BATCH tested. They do NOT parkerize under the FSB. Buffer tubes on Bushmaster are COMMERCIAL aka weaker, thinner, cheaper. Sell your Bushmaster for $900 and go buy a Colt.  Same goes for Rock River, Olympic, and many others. Do the research. Educate yourself.

Using the analytics feature, it has become quite apparent that this video has found itself emailed among many individuals at both DPMS, STAG and other brands I forego recommending here. It is also apparent that many internet trolls from either these companies or friends of, have taken it upon themselves to write vitriolic, emotional and zealous comments that border on insane ramblings, defending these brands and accusing me of being ignorant of the M4 platform. These comments will no longer be posted, so do not even waste your time. I suggest you spend the time improving your product line.
