Found the motivation to finish another P80 today.
View attachment 2401815

Not much different from the first one other than two tone. Sorry I'm not very creative.
May as well either suppress it or stick a comp on it if you're using a threaded barrel.

My P80 17 now lives in a CAA MCK brace setup, which is pretty fun to plink with. Also has people asking what I'm shooting when I'm at the range, which is just a bonus.

Not to PL or give TMI but I'm waiting to move to a suppressor friendly state. The barrel is for the future. Love the MCK brace I have for one of my 19s. Patrician taste man
 

I am a big freedom armory fan boy for a lot of reasons.
direct threaded non-booster suppressors for the AR-15 are generally not full-auto rated, and in an SBR you will not want to go much less than 11.5 or 12.5 because you will encounter significant flame cutting as back pressure from the short barrel will bleed into the barrel after the bullet has exited. either get a short barrel with an improved gas port size (0.0675" for 10.3" barrel through 0.070 for 11.5" barrel) or get a 12.5" with a more normal 0.072" through 0.086" port.

generally, the shorter the barrel and the higher the pressure with a short dwell time, the smaller the port will need to be to avoid issues with either flame-cutting or excessive gas pressure let into the system.

to make things easy:

1. you can usually get a Colt "Commando" LE6933 11.5" barrel and use a carbine or H1 buffer with nearly any direct threaded non-boosted suppressor on the market without much trouble, the gas port is 0.070" and saves you the trouble of swapping buffers for non-suppressed use. older RO933 and Model 733 barrels are usually larger, up to 0.074".

1a. the Colt "HRT" 11.5" barrel has a 0.069" gas port and is intended to be suppressed most of the time, and is more "modern" for 5.56mm ammo (might have issues with .223 Rem if using a carbine buffer). use this with an H1 or H2 buffer.

2. popular is a 10.3" barrel with 0.070" gas port and H2 buffer. 0.070" is the current standard gas port size for the Mk 18 specification with a 10.3" barrel and H1 buffer. 10.5" barrels usually go with a 0.066" gas port (old meta was 0.076" with a carbine buffer) and can be easily sourced from FN or DD. DD tends to use 0.066" for their 10.5" and 0.068" for their 11.5" but new complete rifles are either 0.069" or 0.070". older DD barrels floating around as NOS might be old meta 0.076" and larger.

most other barrel makers like BCM or Windham/Bushmaster is in the 0.073" through 0.076" size which will work reliably with the carbine buffer and even then is slightly over gassed. good if you might sometimes use cheap .223 ammo, bad if you don't want gas in the face or excessive recoil. Aero Precision and Faxon weirdly uses the old 0.079" and larger gas ports as well.

I was thinking back to the scene from The Departed where Jack Nicholson says that people get a life sentence for owning full automatic rifles.

Im surprised they didn't mention Waco lol but looking into penalties for owning a fully automatic unregistered rifle, its like a 10 year sentence and not a life sentence. Though bump stocks have been recently unbanned.

That movie is from 2006 so AR-15s were not as popular as they are now.

The AWB only ended late 2004. It usually takes a couple years to make a movie like that.
 
I hate that Chipman can be completely not qualified for the job and just generally a turbo-NPC of a human, but the thing that might actually serve justice is that he dropped the n-word (oh noes!) at some point in his life.
Cuomo is only being investigated for sexual assault, not all the people he murdered by proxy.

You beat me to it.

The man can be totally fine with Waco-style mass murder as a means of gun law enforcement, you know, the thing he'd be doing in the position they want to appoint him to, but God forbid the man say a certain word in any context whatsoever.

Right? Killing 10K old folks through sheer stupidity and then covering it up isn't newsworthy, but omg he grabbed a boob is gonna end everything for him.

I'm glad that the modern left has its priorities in order

You're forgetting the penalties at the MA state level


(c) Whoever, except as provided by law, possesses a machine gun, as defined in section one hundred and twenty-one of chapter one hundred and forty, without permission under section one hundred and thirty-one of said chapter one hundred and forty; or whoever owns, possesses or carries on his person, or carries on his person or under his control in a vehicle, a sawed-off shotgun, as defined in said section one hundred and twenty-one of said chapter one hundred and forty, shall be punished by imprisonment in the state prison for life, or for any term of years provided that any sentence imposed under the provisions of this paragraph shall be subject to the minimum requirements of paragraph (a).
 
For a long range target shooting setup, what's everyone going with? .270 or 6.5CM? Trying to decide if the higher BC of 6.5CM is worth it. Don't care about the low recoil of 6.5CM, .270 feels like a gentle push anyway.

Define long range for you.
 
I'm not a distance shooter, I was just asking so someone else who is can have the necessary information to help you.
Yeah, probably should've been more specific.

I've done my research already and shot both calibers enough times, but still can't quite decide. Curious about people's experience.

So far on paper 6.5CM sounds slightly better because of less wind drift, better barrel life, and more options for projectiles, but I'm not entirely sold.

up to 1km is into the heavy 5.56 or average optimized .308 territory for distance shooting assuming you're just hitting paper and aren't shooting for points it's more about your rifle and your ability to dial in your environment than it is the cartridge. if you're shooting for points at these ranges or trying for steel challenge, you'll want to "upgrade".

6.5 Creedmoor is much more ballistically stable than 5.56 or .308 at these distances as well, but on the shorter end of the scale and has the happy advantage of being AR-friendly. the cross-sectional external ballistics of the bullets, stability in flight, is usually only important if your environment is the limiting factor rather than cartridge - you can get top quality G7 bullets to roll your own loads for nearly any cartridge you want so don't feel that 6.5 CM would be limiting you, if you, the shooter is doing your part.

when people want to use a different cartridge for this specific task they're usually wanting hand load headroom in the cartridge capacity for bullet selection or a more out-of-the-box solution that's easier to dial in than weeks of hand-loading and testing. that being said, 7mm Winchester short magnum, .300 Winchester magnum, .300 Norma magnum, and .338 Winchester magnum are "good out to a mile" if the shooter is consistent and the rifle has a quality set up.

for what it's worth, for up to 1km where i am (elevation, latitude), i use either 7mm-08 or .300 WM. with .300 WM being my "long range" cartridge of choice with a 208gr Hornady AMAX on top of 77.5gr of H1000. Sierra 175gr on something like 64gr of IMR4831 would be quite gentle, but stout at 1km.

edit: looking through my old notes, the .270 can certainly reach out past 1km with authority with a 150gr spitzer bullet (SMK maybe) and 58gr of Reloader 22 (work up from 55gr until you get to around 3,000 feet/second). however you are basically stretching the brass and burning the barrel out in literally a thousand rounds. IMR3031 can be substituted in lower quantities with a lighter 130gr spitzer at similar velocities to reach a bit further but you're running into issues with downrange environmentals with a 130gr, and the 100gr's probably aren't worth trying.

Thanks, some good ideas here, haven't looked much at .300 Norma or .338. I'm considering .300 WM as well, but so far still leaning towards 6.5CM due to .300 WM being somewhat overkill for paper.
