The Spec1 Synthetic Firearm Lubricant in a 4 oz bottle is SigArms' premium synthetic blend built for shooters who run their guns hard and want lubrication that holds up under heat, cold, and grit. It works on all firearms, from carry pistols to AR-pattern rifles to shotguns, so a single bottle covers a mixed safe. The proprietary anti-wear agent reduces friction and wear by 95 to 98 percent per manufacturer specifications, which is the kind of number that matters on slides, rails, and bolt carriers logging round counts. If you maintain multiple platforms, this is a one-bottle answer for routine lubrication. Pair it with the right chemicals and cleaners for a full bench.
SPEC1 is a synthetic formulation, not a refined mineral oil, and that shows in the performance envelope. It runs across an extreme temperature range of -110°F to 1250°F, so it won't thicken in a Florida winter morning or cook off during a long string of fire. The blend penetrates existing lubricants, which lets you reapply over older residue without a full strip. It will not harden, gum, or turn tacky over time, and it won't attract dust, dirt, or sand, a real concern for anyone shooting in sandy or dusty conditions. SigArms backs the wear claim with Falex testing at 4500 PSI. It's also non-toxic and non-hazardous, made in the USA, which makes cleanup and storage easier than with harsher solvent-heavy oils.
Reach for SPEC1 after cleaning, when you're lubricating the contact points on a slide, bolt, trigger group, or action before the gun goes back in service. A few drops on the rails and a wipe across bearing surfaces is enough; this oil is meant to stay put and keep working through repeated cycles. Range shooters, duty carriers, and anyone who stores firearms long-term will get use out of the 4 oz size. If you prefer a thicker film for high-pressure contact points, the Spec1 light firearm grease pairs with this oil, and you can round out the kit with our universal cleaning kits.
SPEC1 is a synthetic firearm lubricant for the moving and bearing surfaces on any firearm, including slides, rails, bolt carriers, and trigger groups. Apply it after cleaning to reduce friction and wear and to protect metal during use and storage. The manufacturer rates it for use on all firearms.
Yes. SPEC1 is rated to function from -110°F to 1250°F per manufacturer specifications. The synthetic blend won't thicken in cold weather or burn off during sustained fire, which makes it suited to both winter conditions and high-round-count range sessions.
SigArms lists friction and wear reduction at 95 to 98 percent, supported by Falex testing at 4500 PSI. The formula contains a proprietary anti-wear agent and penetrates existing lubricants, so you can reapply over older film without fully stripping the part.
No. The formula is designed not to harden, turn tacky, or attract dust, dirt, or sand. That keeps it from forming the gummy buildup some oils leave behind, which matters in dusty or sandy shooting environments where contamination is a concern.
SPEC1 is non-toxic and non-hazardous, which simplifies cleanup and storage compared to solvent-heavy oils. It's made in the USA and ships in a 4 oz bottle suited to maintaining several firearms over time.
