# FN 15 DMR3 Tactical 5.56 NATO Rifle - Precision Black, 30rd **Brand:** FN Herstal **Category:** Semi-Automatic Rifles **Caliber:** 5.56 NATO ## Specifications - **Caliber:** 5.56 NATO - **Barrel Length:** 18" - **Capacity:** 30 rounds - **Finish:** Black - **Weight:** 118.4 oz - **Overall Length:** 38.5" - **UPC:** 845737015350 - **SKU:** UCEt9uKIQ ## Description The FN 15 DMR3 is a semi-automatic rifle chambered in 5.56x45mm NATO, built around an 18-inch chrome moly vanadium chrome-lined barrel with a 1:8" twist. It ships with the Geissele GS2 two-stage precision trigger, which is a notable factory inclusion. Most DMR-class rifles in this range require an aftermarket trigger upgrade to get that quality of break. ### Key Specifications - **Model:** FN 15 DMR3 - **Caliber:** 5.56x45mm NATO - **Action:** Semi-Auto - **Barrel Length:** 18 inches - **Capacity:** 30+1 rounds - **Trigger:** Geissele GS2 2-Stage Precision Trigger - **Safety:** Ambidextrous - **Overall Length (OAL):** Adjustable from 35.20" to 38.50" - **Weight:** 7.40 lbs - **Stock Description:** Synthetic, collapsible with six positions - **Finish Color:** Black - **Barrel Twist Rate:** 1:8" ### Detailed Features The chrome-lined barrel extends service life and resists fouling better than a stainless target barrel, a trade-off that makes sense for a rifle that might see hard use alongside precision work. The muzzle brake reduces felt recoil and helps keep the muzzle on target during rapid strings. Ambidextrous safety selector and charging handle work for left- and right-handed shooters without modification. The continuous Picatinny top rail runs the full length of the upper, so optic placement is flexible. The six-position collapsible stock adjusts overall length between 35.20 and 38.50 inches depending on the shooter's preference and gear setup. At 7.40 lbs the rifle is not lightweight by AR standards, but the 18-inch barrel and Geissele trigger explain most of that. ## Frequently Asked Questions **Q: What caliber is the FN 15 DMR3?** A: The FN 15 DMR3 is chambered in 5.56x45mm NATO. **Q: Who makes the FN 15 DMR3?** A: The FN 15 DMR3 is made by FN Herstal. **Q: What type of firearm is the FN 15 DMR3?** A: It is a semi-automatic rifle built on an AR-platform. **Q: What is the barrel length of the FN 15 DMR3?** A: The FN 15 DMR3 has an 18-inch chrome-lined barrel with a 1:8" twist rate. **Q: How many rounds does the FN 15 DMR3 hold?** A: It has a 30+1 capacity. **Q: Is the FN 15 DMR3 optic-ready?** A: Yes, it has a continuous Picatinny top rail running the full length of the upper for flexible optic placement. **Q: What trigger does the FN 15 DMR3 come with?** A: It ships with a Geissele GS2 two-stage precision trigger from the factory. **Q: Where can I buy the FN 15 DMR3?** A: Compare current vendor offers on this page. ## What Reviewers Say *Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.* > Fns rifles or ar-15s they weren't bad they just were a little uninspiring. > > — [Colion Noir](https://www.youtube.com/watch?v=YAGyfAGO6wQ&t=19s) > This gun shoots incredibly soft then you add the surefire pro comp on it and the gun just honestly just sits here. > > — [Colion Noir](https://www.youtube.com/watch?v=YAGyfAGO6wQ&t=331s) > I get this nice clean and i mean clean it's about a four pound take up and i know it sounds heavy but trust me it's not. > > — [Colion Noir](https://www.youtube.com/watch?v=YAGyfAGO6wQ&t=544s) > It's such an easy trigger to modulate and when you start shooting for precision you start stretching this thing out to four five six hundred yards you really want a trigger that you can work and predict. > > — [Colion Noir](https://www.youtube.com/watch?v=YAGyfAGO6wQ&t=574s) ## What Customers Say *AI-generated insights from customer reviews* User feedback on the FN 15 DMR3 is consistently positive on accuracy and build quality. The Geissele GS2 trigger is called out repeatedly as one of the main reasons to choose this rifle over comparable AR platforms. Shooters who have used aftermarket triggers recognize the value of getting one from the factory. Groups at distance are frequently reported as tight, consistent with what the 18-inch barrel and 1:8 twist should produce with quality ammunition. The main criticisms are weight and price. At 7.40 lbs before optics and a loaded magazine, it is heavier than a standard AR-15, and some users expected lighter for a modern sporting rifle. On price, the consensus is that the quality justifies the cost, but the entry point is high enough that a few users feel the pinch. Parts availability for FN-specific components has come up occasionally as a concern for shooters who want to modify or repair. Recoil and muzzle rise during fast strings get brief mentions, though most attribute that to shooter technique or ammunition selection rather than a rifle design flaw. The overall picture is a well-regarded precision AR that earns its reputation on the range. ## Pricing **3 offers available** | Vendor | Price | |--------|-------| | Grabagun Com | $2039.00 | | Primaryarms Com | $2039.00 | | Guns Com | $2118.99 | ## Similar Products - [FN 15 DMR3 Precision 5.56 NATO Rifle - FDE/Black, 18" Barrel](https://gunsnation.com/p/fn-15-dmr3-precision-5-56-nato-rifle-fde-black-18-barrel/UCEt9uKIh) - [FN 15 DMR3 Precision 5.56 NATO Rifle - Geissele, Tungsten Finish](https://gunsnation.com/p/fn-15-dmr3-precision-5-56-nato-rifle-geissele-tungsten-finish/UCEt9uKIo) - [FN SCAR 15P Tactical Pistol - 5.56 NATO, Compact Precision](https://gunsnation.com/p/fn-scar-15p-tactical-pistol-5-56-nato-compact-precision/UCEt9uKGi) - [FN15 TAC3 5.56 NATO Carbine - Semi-Auto, 16" Grey/Black](https://gunsnation.com/p/fn15-tac3-5-56-nato-carbine-semi-auto-16-grey-black/UCEt9uJsX) - [FN SCAR 20S Precision Rifle - 6.5 Creedmoor, Matte Black](https://gunsnation.com/p/fn-scar-20s-precision-rifle-6-5-creedmoor-matte-black/UCEt9uJrR) - [FN15 TAC3 Duty: 5.56 NATO Semi-Auto Carbine, 16" Barrel - Black](https://gunsnation.com/p/fn15-tac3-duty-5-56-nato-semi-auto-carbine-16-barrel-black/UCEt9uJs2) --- *Data from [GunsNation](https://gunsnation.com)*
