Introduction
The Sig Sauer 716i Tread is a well-known AR-10 platform rifle that has generated significant interest among enthusiasts and professionals alike. Designed for those who want the power of a .308 round in a modern sporting rifle platform, the 716i Tread promises precision, reliability, and modularity. But, like many firearms on the market, it isn’t immune to issues.
If you’re considering purchasing the 716i Tread, it’s essential to understand the common problems users have reported. Knowing the drawbacks upfront can save you from frustration later—and better yet, most of these issues have workable solutions. Let’s break down the most common Sig Sauer 716i Tread problems and what you can do about them.
Overview of Sig Sauer 716i Tread Problems
While the 716i Tread generally performs well out of the box, several users have reported issues that could impact performance, particularly under rigorous use. Some problems stem from manufacturing inconsistencies, while others are related to component compatibility or break-in periods.
The key issues reported include:
- Failure to feed (FTF) malfunctions
- Extractor and chamber-related complications
- Charging handle tightness or misalignment
- Trigger inconsistencies
- Hammer wear or malfunctions
Let’s take a closer look at each problem and its practical solution.
1. Failure To Feed Issue & Its Solution
Problem:
One of the most common complaints is the failure to feed, especially during the break-in period. Users report that the rifle occasionally fails to chamber a new round, particularly when using certain types of ammunition or magazines.
Cause:
This can often be attributed to:
- Magazines with weak springs or non-standard dimensions
- Ammunition that doesn’t cycle well in AR-10s
- Tight tolerances during the early usage period
Solution:
- Use high-quality magazines, such as Magpul PMAGs, which tend to feed more reliably.
- Ensure you are using clean, brass-cased .308 or 7.62 NATO rounds rather than steel-cased or low-powered variants.
- Allow for a proper break-in period (200–300 rounds). Many users report improved feeding performance after this.
- Keep the rifle well-lubricated, especially the bolt carrier group (BCG), during early use.
2. Extractor & Chamber Problems & Its Solution
Problem:
Another reported issue is failure to extract spent casings, particularly under high round counts or when the rifle heats up. This is usually due to fouling in the chamber or extractor wear.
Cause:
- Carbon build-up in the chamber and on the extractor
- Sub-par extractor spring tension
- Rough or tight chamber
Solution:
- Routine cleaning of the extractor and chamber is essential. Use a chamber brush and solvent regularly.
- Upgrade the extractor spring with an enhanced spring kit if you notice persistent problems.
- If chamber roughness is suspected, consider having it polished by a qualified gunsmith to reduce friction and improve extraction.
3. Charging Handle Issues & Its Solution
Problem:
Some owners complain about a stiff or gritty charging handle, making it difficult to charge the rifle smoothly.
Cause:
- Misalignment in upper/lower receiver fit
- Debris or finish buildup in the charging channel
- Budget-grade charging handles included from the factory
Solution:
- Disassemble and inspect the charging channel for debris, burrs, or excessive finish.
- Lubricate the handle and work it repeatedly to smooth out minor resistance.
- If issues persist, upgrade to an aftermarket ambidextrous charging handle like the Radian Raptor for better ergonomics and smoother operation.
4. Trigger Problem & Its Solution
Problem:
While serviceable, the stock trigger on the 716i Tread has been described as “spongy” or inconsistent by some users. There may also be issues with reset or a gritty feel.
Cause:
- Standard mil-spec trigger group quality
- Lack of polishing or tuning from the factory
Solution:
- If you’re experiencing an inconsistent trigger pull, consider upgrading to a drop-in trigger from reputable brands like Geissele, CMC, or Timney.
- A smoother and more predictable trigger can greatly improve shooting accuracy and comfort.
- If you want to retain the factory trigger, a light polish of the contact surfaces (by a competent gunsmith) can also improve feel without replacement.
5. Hammer Problem & Its Solution
Problem:
A small subset of users has reported accelerated wear or failure of the hammer after a few hundred rounds.
Cause:
- Inadequate heat treatment of the hammer
- Poor alignment or improper engagement with the sear
Solution:
- Inspect the hammer for signs of peening, cracking, or deformity.
- If wear is evident early on, contact Sig Sauer for warranty support—they’re known for responsive customer service.
- Alternatively, consider installing a reliable aftermarket hammer or full trigger group to improve both reliability and trigger feel.
