Got a chance to go shooting today and test out my new EFX-A1 stock. I have been switching out and testing parts for the better part of 6 months while building my rifle. I am officially done and couldn’t be more pleased!

Back to the point of this thread…the EFX-A1.

Initial impressions: The build quality is nice, clean smooth edges and very sturdy feel to it.

Install: I ordered a full kit from stag arms which included everything to go from a carbine gas system to a rifle / A1 system. Install was easy and quick, stock fit up perfect and the whole process took under 10 minutes.

Testing: I loaded 5 proven mags with 2rds each. All locked back as expected. Then I fired 5 30 rd pmags and a few 20 rounders. Again, all were perfect.

Conclusion: For 100 bucks I feel like this was a steal. Great product, great customer service (called MAGS llc twice with questions) and great price.

A few pictures…









I ordered some small bottles to fit in the storage compartment to store oil in. Ill post some more pictures when they come in. Any questions feel free to ask away.
