Jan 11, 2018 · My friend and I are both interested in getting a FN Military Collector M4. After some research, it seems like the most recent batch of FN 'MC' M4 will be correctly marked 'Safe', 'Semi', and 'Auto'. I also seen pictures of the newer batch M4 rifles showing the correct Rolled Marked 'Stick FN' logo, and with correct SC manufacturer information.

Nov 1, 2017 · It's odd that FN sells the replica with the more expensive Knight's Armament RAS, instead of the issued P&S version; probably a contract issue. P&S Products (code 4U486) supplies USGI butt stocks for some time now and is what is on the collector M4 and Colt's LE models as of late.

Feb 20, 2023 · I did do a FN 14.7" CHF lightweight barrel using a FN lower and a FN mil-surplus upper. I also own Colt M4A1's in factory config's. The best buy IMO is Colt when considering the two brands. I've never come across anything FN that resembles Colt M4A1's. As another post stated, I don't think FN has the right to sell this. I'm no way downing FN.

Feb 7, 2023 · Fun fact, basically every FN M4A1 I’ve seen has an FN CAGE coded M4 RAS. I was under the impression the two main manufacturers were (obviously) KAC and P&S. The one I posted right below your post was a factory new gun and had a Colt upper.

Aug 26, 2018 · Can someone please post a FN M4A1 Forged mark? I have a unanodized Aero flat top stripped upper receiver. I want to replace my FN Military series M4A1 upper receiver with a Correct Military markings F next to the Forged mark. I think F next to Forged mark and a smaller M4 above the gas tube hole like Colt M4 Upper receiver?

Apr 5, 2020 · I can say I was impressed the first time I shot a Colt SOCOM barrel. Here is a comparison of a new current production FN M4A1 barrel and Colt M4A1 SOCOM w/ 1000-1500rds... FN bore: Colt bore: To be fair, the FN barrels shoot …

Apr 19, 2022 · I love FN M16s, having seen a lot of them in my early years in the Army and carried an A4. I'd love to have a clone of an FN M4A1. However, I was really disappointed in what FN called their Military Collector series based on the markings they applied to …

Jul 19, 2020 · Which would be correct for the M4A1? Is the same sight used on both the M4A1 and the M16A4? If so then how does zeroing differ for each rifle using the same sight? Are all the forge codes correct for mounting on an FN rifle? Finally, are M4A1 rifles still issued with the detachable carry handle?

Mar 19, 2018 · As far as I can remember the Colt or FN M-4 (3 rd burst) is the standard issue. They are being phased out and converted to the M4A1 (fully auto). It will have the Knight's / P&S rail system as well. The optics was/ is the Aimpoint Comp M2 or M4 CCO or the Acog, not sure what the current one is.

Oct 20, 2021 · FN 6 position carbine extensions are listed as 6061 aluminum. Some FN charging handles are listed as just, "aluminum." An FN bolt carrier group comes with an odd silver colored ejector, while buying just a lone FN ejector gets you a proper black one. 4150 steel has 25% more carbon than 4140 steel while 4140 steel has 20% less carbon than 4150 ...
