The Del-Ton Lima is a semi-automatic pistol chambered in .300 AAC Blackout with a 10.5-inch barrel. It ships optics-ready with no sights installed, so mounting a red dot or LPVO is the expected setup. The 9-inch M-Lok handguard leaves plenty of room for lights, grips, or other rail-mounted accessories.

Features: 

The 1-in-8 twist rate handles both supersonic and subsonic .300 BLK loads without issue. At 4.8 lbs the Lima is light enough to handle for extended periods. The threaded barrel at 5/8x24 accepts standard suppressor mounts, which pairs naturally with subsonic loads. 
 
The A2 pistol grip and hard coat anodized finish are mil-spec components — nothing exotic, but they hold up to normal use. The dust cover and forward assist are included; some AR pistols at this price point omit one or both. 
 

Who it suits: 

• Home defense or tactical use where a compact .300 BLK platform is preferred 
• Suppressor users who want a short-barreled host already threaded at 5/8x24 
• Competitive shooters in divisions that allow semi-auto pistol-configuration ARs

Most owners cite the compact size and .300 Blackout versatility as the main draws. The ability to run both supersonic and subsonic loads from the same firearm is the feature that comes up most, especially among users who pair it with a suppressor.

The optics-ready setup gets positive feedback from people who were planning to mount a red dot anyway. Those who expected iron sights out of the box were disappointed to find none included.

Recoil comes up occasionally — .300 BLK in a pistol-length gas system is snappier than 5.56, and a few users note it takes some adjustment. Ammunition selection matters here; cheap or inconsistent brass can cause cycling issues in any .300 BLK build, and the Lima is not exempt from that.

Build quality reports are generally positive, with most users reporting reliable function. A small number mention minor QC issues, but these appear to be outliers rather than a pattern. Overall sentiment leans positive among buyers who understood the platform before purchasing.
