I've been through 4 M4 Turk clones so far. Utter junk. The pistons and the piston chambers are just not even close to what they need to be. Materials and machining both.

Get a Remington V3 if you want the same operating system but not a Benelli. Prior Remington had the VersaMax as well, but it has been dropped. Even Remington had some QC issues, but most of them ran fine. I designed the feature set of the VersaMax Tactical for Remington, and I was always trying to get them to up the QC and consistency.

The M2 clones are a much better attempt in general. But then the bolt spring and extractors are easy fixes, whereas one can't parts swap an M4 clone (executed poorly) into acceptable.

 

I tried the Panzer Arms-not in spec with (at least some) Benelli parts. No bueno, sold at a loss with full disclosure to buyer.

 

I have an AKSA S4 imported by SDS and sold by Centerfire Systems. I have owned it for a while. Life is busy and I finally had a chance to shoot it with my son in August. I shot about 100 LE low-recoil slugs (a combination of Federal and Winchester) and about 200 rounds of Federal tactical 00 buck through it.

It cycled and shot everything I fed it. I didn't try it to shoot any target loads or garbage ammunition. Accuracy seems to be on point, I didn't shoot over 25 yards. I didn't have a single failure.

I purchased a 7-round mag tube, follower, spring, and a couple of other parts that would make it 922R compliant. I haven't gotten around to installing them yet.

Centerfire Systems has the Aksa S4 for $379 now. I paid $499.

Quick Review of the SDS S4 with some upgrades

As I noted in my Green Ops shotgun class AAR, I am a HUGE fan of my SDS S4 shotgun. This is a Benelli M4 clone that, unlike the previous M2 and M3 clones, is damn near perfect in. Read on for some …

Hope this helps.

 

Life is too short to suffer cheap knock off junk.

 

I am debating ordering one. I thought the issues were with the butstocks needing to be replaced with real Benelli or Messa ones.

Shot M4 Benelli this weekend, with a few others to test out some Black Aces GT9 buckshot at 1450 fps. Those rounds might tear up copies… and I think the ammo is from Turkey.

 

Turknelli M4 clones, any one lucky?

I’ve never purchased one. I guess that makes me lucky.
