Most Helpful Negative Review Disappointing Experience with the Sylvan Arms AR-15 Flared Magwell
I recently purchased the Sylvan Arms AR-15 Flared Magwell, and I must say that my experience has left me thoroughly dissatisfied. While I had high hopes for this product, it turned out to be a significant letdown for several reasons. First and foremost, the compatibility issue was glaringly apparen...

DOES NOT WORK WITH PMAGS

by k-Roll, Verified Owner from NH, United States Written on February 20, 2026
I had high hopes for this product. I wasn't thrilled that it was an integrated trigger guard also, but I gave it a shot. Installation was fairly easy and the product seemed to be made well. Once installed it felt very solid. Note: I noticed there was a paper-thin gap between the firearms mag-well face and the device itself. I didn't care one way or the other about this as it doesn't seem to be a problem. However, the design of it DOES NOT allow for P-MAGS to fully insert without considerable force. Perhaps the space previously mentioned was the problem and some hammer and vise modifications could make it work? The P-Mag has raised ridges on the non-insertable portion of the outer body that interfere with the mag-well device. Specifically, the top horizontal raised edge at the magazine's insertable terminator. You CAN get it in there with a lot of force, but you'll have to get it out don't forget. PMAGS are the most popular magazine on the market today making this potentially a MAJOR oversight by Sylvan design engineering and quality control departments. With that said, basic metal MILSPEC type magazines work just fine but, in a gunfight, I do not want my hands tied as to what magazine will work and what one will not. Fix this issue and I'd gladly revise my review to 5 stars. I kept it just because I didn't want to go through the aggravation of returning it, so its basically money down the drain.
Pros:
  • Sturdy
  • easy installation
  • Works well with metal milspec magazones
  • pleasing design
Cons:
  • integrated trigger guard
  • space present between device and firearms magazine well opening
  • Doesn't fit P-MAGS
Best Used for:
  • Use with metal MILSPEC magazines

LWRC lower beware

by Pancake, Verified Owner from VA, United States Written on January 3, 2026
If you have a LWRC lower and plan on using Magpul mags, stay away. The build quality is great but if it doesn't fit a magazine then it's useless.

Works but there is a caveat….

by an honest reviewer, from TN, United States Written on June 10, 2024
I would recommend you use metal mags with this product. In my experience if you use plastic ones from Magpul, they tend to get stuck and you have to yank it out. I used the duramag magazines in my 7.62x39 AR with this attached and it is able to work well. Overall installation was painless and the fit is good enough on my PSA lower.
