    The AR assembly thread

    I hate people calling AR’s “built” when they screwed some parts together. 80%’s count. So let’s see your latest or past AR assemblies and parts lists. Can be a place for stupid newbs to ask dumb questions also.

        A note for people putting together an AR...

        1) RISE triggers do NOT work with Timber Creek Safety 45^ levers, will not safe.
        2) The same TC safety levers seem to have a issue with SOME CMC triggers, however I have a limited example to test with. (Edit 1)


        I will add to this as I come across other little tidbits and tips.

          80% lower, timney trigger, magpull grips and stock, Troy handguard, 16" Ballistic Advatage (maybe) barrel, Precision Armament EFAB brake, Primary Arms 1-6 scope with ACSS reticle. It's my go-to for 3-gun and shoots super flat, and accurate out past 400yds with 77g ML262 ammo.

              Nothing special.

              Top is my “Parts Box” build.
              Stripped lower was a gift from my brother, upper was a gift from another brother. Anderson M4ish barrel (another gift). Butt stock, handgaurd, barrel nut and delta ring, gas block and tube, muzzle brake, Burris Gast Fire III, pistol grip, upper/lower parts were all left overs from my brothers builds. Only thing I had to buy was the BCG, a PSA blemish, for $74 including shipping.

              Middle is a bone stock ‘73 vintage SP1 my dad picked up in ‘78, gave to me a couple years ago. It was in between the other two in the safe, so it’s got in the picture as well.

              Bottom is a TAC poly lower, PSA blem upper, Dead Shot Barrels 16” .338 Federal barrel with whatever adjustable gas block they use, no name A2 buttstock, PSA BCG, and PSA upper and lower parts kit. Still need to pick up a hand guard (or at least a barrel nut) and some dies to make it go bang.

                I’ve been in to short barrel firearms for quite some time. My first was the Bushmaster Carbon 15 Type 97 Pistol. A fairly dismal affair, I would have sold it a long time ago if not for my “never sell a firearm” policy. It was unique because it met all of the requirements for a pistol that were in force at the time. Less than 50 oz., no handguard, shot from one hand only. As such, the upper and lower receivers are made from carbon fiber. It had a proprietary buffer/buffer tube and barrel and muzzle brake. I quickly learned two things: no AR15 should be made out of plastic and no 5.56X45 NATO round should ever be fired from a 7” barrel. You absolutely need ear plugs AND muffs shooting it. It spits a huge fireball and gives you a big thump to the chest. It was not that easy to shoot well either.

                  As regulations eased over the years, it’s morphed into this. It’s much easier to shoot, but still quite an asshole. It’s only redeeming value is that it’s still quite light: 4 lb., 13 oz.

                    Next came the Mossberg 12 ga, Shockwave. I know, I know, it’s not an AR15 but still… It was huge fun to shoot but hard to shoot well. Adding the SB Tactical brace, Crimson Trace laser saddle, and shooting minishells with the OpSol adapter made it into a very competent home defense gun.

                        Then came the .300 ACC Blackout cartridge. It was designed for a 9” barrel, available in 200+ gr. subsonics and 90-125 gr. supersonics. With the same case diameter as the 5.56, the gun shares many parts with the standard AR 15 and the same magazine capacity. The ammo is relatively cheap too, not 5.56 level but $0.37 to 1.00+ per round.

                        I pulled out the two S&W M&P lowers I had laying around since Obama’s first days in office and order up 8.5” and 10.5” uppers from Palmetto State. I had many of the rest of the required parts in stock (including the C-More Railway red dot sight) to make two shootable firearms, but the other upgrades probably tripled the cost of each. Both have Franklin Armory Binary trigger systems (100% legal fun switches) and JP Enterprises Silent captured springs. And the Q Trash Panda sound suppressor.

                        Shooting suppressed, you are amazed by the amount of noise the recoil system makes in an AR15, the JP recoil system really quiets it down. Small bits include finger stops, labeled dust covers, and QD end plates. The 10.5” gun also got a Vortex 3X red dot sight.

                        The 8.5” gun is tuned for suppressed subsonics and the 10.5” for supersonics, but either can shoot both flavors, suppressed or not. The 8.5” gun now has the heaviest spring in the JP tuner pack and two tungsten buffer weights; I’m currently tuning the 10.5” gun. I am definitely not in the “never leave an M- LOK slot unfilled, tacticool as fuck crowd – exactly what you need and nothing more.

                          Nice. I have an 8.5” .300 Blackout as well, need to take a pic of it and I’ll post it up. With an H2 buffer it’s run everything I’ve fed it, from 220 subs to 125 superstar.

                            Thought I had a parts list somewhere, but can’t find it. It’s a PSA 8.5” upper, I went through it and drilled/locktited/staked the gas block. It’s got a Midwest Industries 9” handguard with their blast diverter, Troy sights, lighter weight polished trigger, Sig Romeo 5 red dot, SBA3, Springco red spring and H2 buffer. Fits in a small backpack with 3 mags as my truck gun.

                              16" carbine odin works BBL and BCG, BAD lightweight upper lower and handguard, MFT stock and grip, KME trigger, JP captured recoil spring, and primary arms 1-6 ffp scope.
                              Turned out really light with a lot more punch than 223, which is what I wanted.

                              20" rifle odin works BBL and BCG, Aero upper and lower, geisley handguard, timney trigger, Fagpull stock and grip, JP recoil spring and SWFA 16X scope and rings.
                              Haven't shot it too much yet, would like to get it out to stretch it's legs out to 500 yards.
