Does not work with pmags - Sylvan Arms AR-15 Flared Magwell

k-Roll's Review of Sylvan Arms AR-15 Flared Magwell
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
Would Recommend:
No
