Re: Weaponizing the AR15

The ammo shortage has brought testing to a crawl until I can reload some 5.56. To a crawl? Yes...but not to an absolute halt. ;) My current goal for a run and gun competition AR is to get one entirely dialed in for USPSA minor power factor ammo. Minor? For those new to USPSA multigun, it is worth po...

SHTF or competition build focus?

I probably should have broken this up into two threads but highlighting the differences is some times very valuable info as you can cover what to do on one while also hitting “never do this” on the other...

Split em up or leave both in the same thread?

Re: Weaponizing the AR15

A quick check (combat vs. competition): Take your bolt carrier group out of the AR, grab the bolt and pull it as far forward as it will go (while still in the carrier) and then set it upright on a table with the bolt on bottom... If you have a SD/SHTF AR, you are running a full weight M16 bolt carri...

Re: .300 blk pistol help

Did you install the gas block yourself? Just curious if maybe the gas port is partially blocked. That is a certainly something that needs double checked. If you seat most gas blocks right up against the shoulder on the barrel they will be at least partially obstructed. A 0.020” - 0.025” spacer need...

Re: Weaponizing the AR15

Added some new upgrades to my 18” AR today - they are very likely comp use only but if you are a comp shooter...the gun feels amazing.

I will be fully testing them this weekend.

Re: .300 blk pistol help

-10% spring might fix it. In the alternative, you could try replacing one or two steel buffer weights with aluminum buffer weights https://www.kakindustry.com/ar-15-parts/lower-parts/buffer-tubes-and-parts/buffer-weight-aluminum That’s possibly a dirt cheap fix but a lighter buffer may be more of a ...

Re: .300 blk pistol help

Try a -10% power buffer spring or -20% buffer spring. It’s hard to say as port diameter for gas is all over the place (depending on manufacturer nowadays) - I would order and test the hell out of both but I am OCD like that... Accurate port size requires a pin gauge for a really accurate reading so ...

ARs that Shave Brass

I haven’t seen too many properly gassed ARs that will damage brass but I have seen a few. Usually, it is due to an burr or edge that was left on the verge of razor sharp by the manufacturer. I reload .223/5.56 and, while finding brass is usually is fairly easy, the occasional election and/or pandemi...

Bolt Upgrades

If the AR design has an Achilles heel, it is very likely the bolt. The US military rates average AR bolt life as a mere 7,500 rounds but many which are not used in burst fire last much longer. While most of them will not fail until they have fired more than ten or twenty thousand rounds, having a sp...

Re: Weaponizing the AR15

Back to a some DIY tuning - The bolt is often another area that can benefit from a bit of polishing. I typically polish all the flats on the bolt with a Dremel and felt wheel loaded with Flitz or Maas polish. It doesn’t take much but can smooth cycling considerably: ABC5F360-0B5F-447A-81DE-FE42EE878...

Re: Weaponizing the AR15

Tuning a competition AR’s gas system is a little different than that for a SHTF/defensive AR. For a competition gun, you load one round into the mag and then fire the one round to see if it locks back on an empty mag. Then you rinse and repeat after restricting the gas until the rifle will not lock ...

Re: Weaponizing the AR15

Other notes on gas tuning. Most manufacturers of lightweight bolt carriers recommend an adjustable gas system to ensure proper functioning but there are some BCGs that also let you tune the gas on the BCG side. Example: RCA’s Ultralight Titanium BCG with adjustable gas key: https://rubbercityarmory....

Gas System and buffer weights

It occurred to me that I have just scratched the surface of AR tuning and the things you have to balance out so I will dig a little deeper into that... Cycling of an AR is three pronged: 1. Gas (port size and gas system length - if you want to get really picky, you could also throw compensators in h...

Re: Weaponizing the AR15

Speaking of bolt carrier groups, for a competition AR, a lightweight bolt carrier is a great upgrade. A typical milspec BGC is about 11.6oz which is quite a bit of reciprocating weight. You can find lightweight carriers that are anywhere from around 5.8oz up to 9.5oz. The lightest often lose forward...

If you get or have an upper receiver that looks like this (i.e. fairly rough machine marks): 794B0F4E-0218-4BDF-9F56-EA9024575612.jpeg You can smooth it up quite a bit by very lightly polishing the contact points for the rails on the bolt carrier group with 3M paper.
