where do you find an upper like that?

what else can you tell me about that configuration?

If it is just for subs, makes you wonder if you couldnt sort out a blow back bolt carrier so you could shoot it both ways.

LAR Grizzly upper
Apex handguard
Ported Mike Rock 1-8" twist barrel
Built by SRT Arms

What else do you want to know?


thehouseproduct, it is set up for subsonic only. I hadn't thought about that but might have to look into it. It probably wouldn't be nearly as quiet, though.

I looked at LAR's website earlier, it appears that the upper is normally a gas operated upper, so did you install an adjustable gas block, or just use a non ported barrel?

I am crazy nuts about that forearm

What's nice about this forearm is that it clamps over a standard barrel nut. Normally the clamp would be offset to allow room for the gas tube and keep a slim profile but I had them make a concentric clamp so the suppressor would be centered. I think it's now a standard offering but I paid a huge premium for this clamp.

So, there is no gas tube then?
How is the extraction& ejection effort?

I shot this over the chronograph today with my standard load (9.2 grains of #9 & 220 gr. SMK) and only got 860 fps. My 12 " gun gives about 1030 fps with the same load. That probably helps explain why it was so much quieter. I'll work up some faster loads when I get a chance.

Correct, no gas tube.

Operation is smooth and easy. The side charger seems to require less effort than the standard rear charging handle. I just have to remember to use it. You wouldn't believe how many times I've pulled the trigger and had nothing happen because I'm so used to semiauto.
