G5 Montec Review: Flight, Cut and Verdict

The G5 Montec is a three-blade fixed broadhead made as one piece of steel: there's no blade to come loose, and when it dulls, you sharpen it. This G5 Montec review covers every version, G5's resharpening method, and how it stacks up against the Magnus Stinger, QAD Exodus and Montec M3. Our verdict: it's a durability-and-maintenance head rather than a wide-cutting one. If that suits you, compare G5 Montec listings on Amazon or G5's own store.

G5 Montec specs and variants

From G5's product page and store, read 15 October 2026.

The cut figures don't fully agree. G5's product page says "1.0625″ Cutting Diameter" (and later "1.0635″", which looks like a typo), while the store gives a range. Lancaster's Pink Montec listing hints that lighter heads cut slightly less; G5 doesn't say.

Design: one piece of steel

G5's product page describes "3 deadly blades machined from a single premium piece of solid steel", while the store says "One-Piece MIM Construction" (metal injection moulding). Either way, tip, ferrule and blades are one part: "With no components to assemble or replace, simply screw on and shoot."

Heads with separate blades rely on screws, clips or collars; the Montec has none, so it can't shed a blade on bone. The cost is maintenance: when an edge rolls or chips, the whole head goes on the stone.

All three edges run to the point, so it starts cutting the moment it touches hide. G5 doesn't publish a blade angle or head length, whereas Magnus lists Stinger lengths of 2 to 2-3/16 in.

The Montec CS uses carbon steel, which G5 says makes it "incredibly sharp" and "easily re-sharpened after repeated use", with an "Additional Honing Process to Maximize Blade Edge". The Pink Montec is the same design in what G5 calls "pink stainless steel" with an epoxy colour finish.

Sharpening the Montec, the way G5 describes it

Resharpening is the reason to buy a one-piece head. G5's instructions are written for its Flat Diamond Sharpener, which has "ROUGH-600" and "HONE-1200" sides.

1. Mark the edges. Cover all six cutting bevels with a broad felt-tip marker.
2. Set up the stone. Flat on a table, ROUGH-600 side up, with a towel underneath.
3. Grind one pair. Lay two bevels flat, nose away from you, and push side to side with moderate to heavy pressure until the ink is gone.
4. Rotate and repeat. Turn the head 120 degrees for the next pair, then the last.
5. Finish lightly. Give each pair 3 to 12 side-to-side passes with very light pressure.
6. Hone (optional). Repeat the light passes on the HONE-1200 side.

G5's test for "very sharp and very functional" is slicing a stretched rubber band in one pass. It also advises not letting a Montec get too dull, and practising with the Pre-Season Montec.

Setup: spine, FOC and practice heads

The Montec screws into your arrow's insert like any threaded head. Before season:

• Check spine and FOC. Going from 100 to 125 grain moves the balance point forward. Easton recommends "a 10-15% F.O.C. for hunting setups" and warns that "Excess FOC will also cause a given arrow to have a lower dynamic spine". Our arrow FOC guide shows how to measure it.
• Spin every arrow. G5 spin tests each head, but an out-of-square insert can still make the arrow wobble.
• Practise with a match. G5 says the Pre-Season Montec is "dimensionally identical to the Montec", with rounded edges and a black coating; the BMP is "a ballistic match". Our practice broadheads guide explains why you should still finish with real heads.

If Montecs and field points don't group together, see why broadheads hit differently from field points. For crossbows, G5's FAQ says that with its fixed heads "there is no difference between the compound and crossbow versions"; follow your crossbow maker's point-weight rule. Our crossbow broadheads guide covers the checks.

Third-party tests

We found two relevant named tests, and neither covers today's standard Montec.

Outdoor Life, 2015 (Todd Kuhn and Tony Hansen). Their 29-head test, shot from a bench-rested 185 lb crossbow, scored integrity (shots through six 5/8 in sheets of drywall), microscope-checked sharpness, penetration into Ethafoam and more. The Montec CS scored 83.47: "noticeably sharper than previous models", though "extra-large vents seemed to limit penetration in our test". Several fixed heads scored higher, including the QAD Exodus at 89.58.

Outdoor Life, updated 2023 (Scott Einsmann). The sibling Montec M3 "did not shoot a 3-inch group due to a flier" at 40 yards. The original Montec wasn't included.

How it compares

Push force is what it took Einsmann to push each head through doormat, foam and faux leather, so lower is better; he noted the Exodus didn't do well there. Durability meant a shot into PVC pipe.

G5 Montec vs Montec M3

The M3 is G5's newer one-piece head. Its store listing describes a closed-vent design for quieter flight and "an even stronger stainless steel", a 1-1/16 in cut and 100 or 125 grain weights, plus a BMP practice head. Choose the original for the 85 grain option and the Pre-Season practice head.

G5 Montec vs Magnus Stinger

The Stinger is a two-blade cut-on-contact head. Magnus lists its 100 grain at 1-1/16 in, about the same as the Montec. Stinger main blades can be sharpened or replaced, and Magnus promises that "if you ever break one, it will be replaced". The Montec's case is three blades and no parts at all.

G5 Montec vs QAD Exodus

The Exodus is wider: three .040 in blades, a 1-1/4 in cut, and a body Lancaster's listing says matches "the length of a field point". Einsmann found its blades "easy to replace", and it grouped well and passed durability. Choose it for cut width and blade swaps; choose the Montec if you'd rather sharpen than buy blades.

Who should buy it, and who shouldn't

Good fits: hunters who maintain their own gear; households shooting both crossbows and compounds; anyone wary of mechanicals (our fixed-blade vs mechanical broadheads comparison sets out the trade-offs).

The Montec's listed cuts clear the 7/8 in minimum some states set. Washington bars big-game hunting with fixed blades "with less than seven-eighths of an inch cutting diameter", and for game mammals Oregon says "Broadheads must be non-barbed and at least 7/8" wide." Rules checked on 15 October 2026; this isn't legal advice and regulations change, so confirm with Washington's WDFW, Oregon's ODFW or your own state wildlife agency.

Where to buy

G5 sells the Montec through its store and dealers. Its online sales policy says resellers need written consent to sell on Amazon, and its warranty covers the original owner with proof of purchase, so check the seller before you order.

Frequently asked questions

Can you resharpen G5 Montec broadheads?

Yes; that's the point of a one-piece head. G5's instructions use its flat diamond stone: ink the six bevels, grind each pair flat until the ink is gone, rotate 120 degrees between pairs, then finish with light passes and an optional 1200-grit hone.

What's the difference between the Montec and the Montec CS?

The CS is carbon steel, with an extra honing step that G5 says maximises the edge and makes it easy to resharpen. It comes only in 100 grain with a 1-1/16 in cut. The standard Montec comes in 85, 100 and 125 grain, plus crossbow models in 100 and 125.

Is the G5 Montec or Magnus Stinger better?

Neither wins outright. The Montec has three blades on one piece of steel; the Stinger has two or four, with main blades you can sharpen or replace, and a lifetime guarantee. Their 100 grain cuts are similar. Outdoor Life's 2023 test passed the Stinger for durability but didn't include the original Montec.

G5 Montec vs QAD Exodus: which cuts more?

The Exodus. The Full Blade head cuts 1-1/4 in with replaceable .040 in blades, against roughly 1 to 1-1/8 in for the Montec, and it's built short to match a field point. The Montec's advantage is that there's nothing to replace, only edges to sharpen.

Can I shoot a G5 Montec from a crossbow?

Yes. G5 sells crossbow Montecs in 100 and 125 grain, and its FAQ says there's no difference between compound and crossbow versions of its fixed heads. Use the point weight your crossbow maker specifies, meet its minimum bolt weight, and confirm broadheads and field points hit together.
