Each link opens the video at the moment quoted.* > A lot of people mistake longer barrel for more accuracy that's not always the case you can actually have a more accurate shorter Barrel. > > — [Honest Outlaw](https://www.youtube.com/watch?v=6gbhBcaXukM&t=119s) > We shot 120 rounds through it and two things on the rail rattle loose. > > — [Honest Outlaw](https://www.youtube.com/watch?v=6gbhBcaXukM&t=884s) > Gonna feel almost no recall at all when you shoot it and it's gonna be very very smooth and very quick. > > — [Honest Outlaw](https://www.youtube.com/watch?v=6gbhBcaXukM&t=942s) > This is not one of those things that you're going to buy just for your first rifle. > > — [Honest Outlaw](https://www.youtube.com/watch?v=6gbhBcaXukM&t=908s) > A 20 inch rifle was the only thing I had for home defense I wouldn't be pissed about it like you can use it very easily. > > — [Honest Outlaw](https://www.youtube.com/watch?v=6gbhBcaXukM&t=824s) ## What Customers Say *AI-generated insights from customer reviews* Most discussion around the FN 15 M16 Collector splits between the historical appeal and the practical shooting merits. Collectors appreciate that FN has produced the full-length 20-inch configuration that most modern AR-15s have moved away from, and they note the build quality lives up to FN's manufacturing reputation. Shooters praise the 20-inch barrel for its accuracy at distance, where the longer sight radius and additional velocity pay off. The chrome-lined bore and FN's quality control come up consistently in reliability discussions. The price is the main friction point. Buyers weigh it against other AR-15 options in the same caliber. Weight and the full-length profile also come up; at 8.2 lbs it's not a lightweight carbine, and some prefer a shorter platform for most uses. Overall, people who want the M16-specification rifle tend to be satisfied with it. ## Pricing **7 offers available** | Vendor | Price | |--------|-------| | Kygunco Com | $1774.89 | | Buds Gun Shop | $1779.49 | | Guns Com | $1779.99 | | Gunbuyer Com | $1819.00 | | Grabagun Com | $1819.00 | | Shootingsurplus Com | $1819.00 | | Gritrsports Com | $1819.00 | ## Reviews **Average Rating:** 5.0/5 (1 reviews) > **kipper22** (5/5): After about 2 months with this FN, I have no complaints.
