I just thought it was a good deal for an FN barreled upper. And I always kind of had an itch for the shorter length, but didn't really want to go through the SBR nut roll. So 14.7 is about as short as practical in that regard.

How much louder than a 16" or 18"? Can you tell a noticeable difference?

How much louder than a 16" or 18"? Can you tell a noticeable difference? On any given day I have guys with 10.5", 11", 14.5," 16", and 18" M4's. You can't really notice a differamce between 14.5 and 16 or 18" barrels. Having said that, they're all permanently damaging with but a single unprotected shot, so one being "quieter" doesn't really matter. There is a noticeable difference in blast between the 10.5 and 11" guns and the 14.5" and longer, but again they're ALL permanently damaging with a single round being fired.

"What was that?"
So, no real differences in muzzle blast either once you reach 14.5 or so?

In my experience a 16" barrel with no muzzle device is a helluva lot louder than this 14.7 with the A2 birdcage.
I don't find this obnoxious at all with the A2 device up front.

That's good to know. A shorter truck gun would be fun and useful.

A buffer likely will get you where you want to be based on your findings thus far. Albeit the cheapest alternative I too prefer and adjustable gas block. SLR is always a great choice but more and more I am liking both of my Suprelative Arms units.
Suprelative s unit can damper down gas the standard way by restricting gas into the block, they also have a hybrid mode. In these settings full gas enters the gas block yet gas to the gas tube is restricted with the excess exiting the block by way of an exhaust port in the front of the gas block.
This is especially nice for suppressor use Tagging this one for suppressor use. Thanks, Mallard.

It tosses brass all over and into the heater vents. Not to mention the pistol grip and mag well refuse to ride between the seat and center console comfortably. Travis

We can't actually shoot "in or on" a motor vehicle here, so it necessitates getting out anyway.
My truck doesn't have a center console either, so I just throw a rifle muzzle down on the floorboards or chuck it on the floor behind the seat (usually the latter).
The tractor cab in the summer is really where it would get more everyday use.

Okay, I believe I've got this rig dialed in. Finished it up with a Primary Arms 5X prism sight with an 800 yard reticle, and a Magpul MOE rifle buttstock. I like the way it looks and feels. Rain is on the way, and I'll get some more trigger-time soon, without concern for starting a fire.

Nice looking, dialed in now, how well is the barrel shooting?

I have hearing aids now, and I shot a lot of 5.56 without hearing protection when I was a lot younger. I have hunted recently with 16 inch guns with the birdcage on the end, honestly for 1 shot it did not seem to bother, 1 shot = 1 deer, on the other hand I wore out a bunch of pigs one day and the reason I stopped shooting was not because there were no more pigs, nor because I out of cartridges. These days I keep a pair of cheap howard Leigh electronic ear pro on my cap, I know there are better models and I tried the pro ear's gold but am not impressed with the battery type, nor its performance, one ear has a buzzing sound for 4 times the money. I hope to be able to afford sordin's one day. I am intrigued by the DD SLW light weight barrel with 14.5 pinned, its a lot lighter and I have had great experiences with their LW barrels. Another on the wish list!

Nice looking, dialed in now, how well is the barrel shooting? The fire conditions have been so bad the last month I haven't shot it, or anything else lately. We have some rain on the way over the next four days or so. That should help douse some of the wildfire around here, and I'll get back out there and do some more shooting. I think it will shoot well for a chrome-lined AR-15. By that I mean 1.5 moa or so with M855. I'll put together some handloads with Hornady 75gr BTHP and see how they do, probably a little better than the M855 I would imagine. The last time I shot it I had just put the rifle recoil system back on it and that solved my extraction issues I'd been having with the carbine recoil system with 3.0 oz buffer.

With the cool weather and moisture I got this carbine out to test a few rounds, and zero the optic. Pretty breezy today so I decided to reduce the wind effect by zeroing my 200 yard reticle index at 50 yards, knowing 50/200 line up well with the AR. Considering 15-25 mph winds, I'm happy with the accuracy I saw. After zeroing, I ran the M855 on some rocks out to 670 yards. The reticle on the Primary Arms 5X works very well.

What optic do you have on the rifle? I don't know how PSA does it at the prices they sell for. The FN barrel does not shoot bad at all. Wish they made a 14.5 LW floated upper.
