Quote HistoryI remember when Brownells offered that rifle, but this upper was different. I saw the photo in then product page and read the description. It had a 14.5 Socom/Heavy CHF barrel with a 15" Mlok rail that covered the muzzle, but the pinned flaming pig fit under the rail and extended about an inch past the rail. It seemed like their take on the Noveske infidel.

Quoted: Should have grabbed the OEM Delta ring assembly from CDNN. That was one of the things I got to get up to free shipping. Can’t really tell quality by looks alone, but it looks like it’s from the same manufacturer of BCM’s Delta assemblies. Possibly even Colts. The finish, the C clip, and the spring looks identical, and you’d be surprised how much they can actually differ in appearance from one manufacturer to the next. Just a simple part, but I’m pleased. I was afraid it look and feel cheap, and I’m pretty ocd about every little part. |

Quote HistoryQuoted: To be honest, I forgot to buy the delta ring set, A2 flash hider, and gas tube through CDNN. I bought the barrel when I got up at 4 am to go to work. I did get the free shipping because I added a Beretta 92F seventeen round OEM magazine from them for $23 USD. I ended up getting all the parts to finish that upper from Right to Bear Arms again.

Quote HistoryQuoted:
Well, here’s some accuracy results. This is just practical accuracy. I used cheap brass surplus ammunition, an Aimpoint Comp M4s, and was kneeling unsupported. I used the same bolt, optic, and lower for each group to keep it fair. I did not fool with sighting in the optic for each upper.I had about a half hour to burn, so this is all you all get lol Nothing special, and I didn’t even take the time to measure MOA. Sorry. Honestly, they all 3 performed very well, other than the Colt at 100, and I’m 99% sure that was me and not the barrel. It was muddy as hell, getting dark, and my range goes down the side of a wooded ridge. Under better conditions, resting on a bench, and with magnification, I’m positive the results would be much better. Practical accuracy is important to me though. I don’t do a lot of bench shooting, and if I can be at around 3 MOA with cheap brass, I’m happy. Anyways, here it is. All barrels are 14.5” Socom profile with an A2 flash hider on an SBR BCM lower. The BCM has had about 2,000 round through it. This is the first time I’ve shot the Colt and Remington. Both were just recently built. Also want to note that the Comp M4s is practically a 3 MOA for me with my slight astigmatism. It’s not as sharp as it should be. I should have my first Eotech Monday. Hoping it’s a better optic for me. 75 Yards. 10 shot groups. Federal American Eagle 223 55g FMJ.

I’ve been following this thread and convinced myself to buy an 11.5” Rem. So I go to CDNN and thought they raised the price to $199.99. Well, they didn’t.
It’s an 11.5” Rem with what appears to be the same specs but different markings, well, maybe the same markings but in different locations. Interesting… CDNN |

I don’t think this has been answered yet, but I found out REP stands for Remington English Proof. It means it’s been tested to meet SAAMI standards. Not sure what that means for the barrels that don’t have it. Maybe they are the Philippine contract barrels, and the REP marked barrels are for the US market.
Eta: looks like Remington use to proof mark their USGI and foreign military contract firearms with just a “P” in the past. So, as mentioned above, it’s likely the P marked barrels are from previous mil contracts and foreign contracts, and the REP marked barrels are for domestic sales. I could be wrong, but that’s based on how they’ve marked in the past. Edit: “P” could also stand for 2018 production. I reckon I’m going to be the sucker that spends an extra $20 on the other 11.5” barrel. I’m going to chop it, so the location of the markings are worth the extra $20 to me. I don’t think they are REP marked. I’ll share the details once I get it. |

Quote HistoryQuoted: If the markings truly are under the handguards, and this isn’t the usually CDNN bait and switch, $20 isn’t an issue for those that want to cut it down while keeping the markings. I wish like hell I would have got the barrels for $99 or $129, but even at $179 they appear to be worth it. They’ll definitely be worth it if more don’t hit the market. Hell, people are paying close to $300 for them on gun broker. Like I said, as long as Remington doesn’t flood the market with them, they’ll retain value and some. |

Got my 11.5” barrel from CDNN and my 14.5” back from John Thomas. Both look great and will post pictures tomorrow.
The 11.5” is much nicer that the 14.5” barrel. On the left side of the barrel just in front of the FSB is “070” for the gas port size, and on the right the markings are “REP.” |

In all seriousness, bbls appear to be identical other than the markings location as stated. It'd be nice to know the history on these 11.5s.....M4A1 they are not. And I'm fairly certain that there is zero ability to mount a 203 to these. Starting to wonder if these are chopped 14.5s in an attempt to jump on the 11.5 train that the Colt FBI bbls got rolling ? |

Quote HistoryQuoted: I would think a check of the muzzle for how the chrome looks as it exits the inside of the barrel, and a check of the gas port size, could provide insight on the question you raise. That said, Remington offers 11.5 barreled rifles and that length is very popular in the .gov world for LEO and other applications, so I suspect they started life as 11.5's and were not cut down. But why the milled flats? Eta: and looking back, GP diameter is correct for 11.5 and bore chroming showing on muzzles is consistent with new production bbls , like you stated. So, I'm stumped. |
