i also own a guantlet for pests. good to 75 yds 1 inch group

smooth as silk. preset to shoot pellets at 830's. 5o yds 3/4 group 100 yds 1 1/2 group. beyond that things get crazy. slugs in 67 grain 50 yds 2 1/2 group. hoping to tune that out


By BernardUSAFebruary 27, 2021

I believe buying the .357 then adding barrel kits is the way to go. I am waiting for a 30 cal barrel kit to come in.

This Impact X .35 caliber is extremely accurate. I love the smoothness of the cocking leaver and the trigger is super. The Best speed for the 81 gn pellet is 840 to 850 fps. Plenty of power to take down even large game with head shots. I hope to get the 68 gn Fx hybrid slugs when they come out to see how the shoot in the X barrel. Because of winter I have not been able to get to the range and try out the Neilson 79 and 93 gn slugs. At my 25 yard range they are excellent.

When I received the Air Rifle it had a severe leak. I sent it to FX USA and they had it back to me in less then two weeks. FX service center is excellent and they deserve a 5 star rating for their service.

Adam from USA

what do I need to make it ready to shoot

asked Tyler from USA

Can you use slugs right out of the box w/ .35 or do you have to change out to a slug sleve..?

asked ZACHARY E from USA

Does this come with the FX Slug Power Kit?

asked Douglas from USA

Will there be an option of converting to arrow assessable barrel?

asked Michael from USA

Hi what is the thread pitch for the .357 impact. For an aftermarket moderator like the Dony FL

asked Howard from USA


Oliver from USA


John from USA

Can you order a Dony FL Emperor Sound Moderator instead of factory model and what thread pitch is it to match 800 barrel?

Greer from USA

Hey guys what is the thread pitch for an aftermarket moderator like a DonyFL

asked Howard from USA

The case that the .35 comes with, is it similar to other custom FX cases or is it some after market knock-off case?

asked Jeff from USA

It's just a generic case with egg crate type foam. No fitted case for the 35...

Dothan from USA

How long did you have to wait to receive your 35cal impact and was it worth it?

asked Tyson from USA

I bought two, one from here and one from Utahairguns. Both took about 3 months to get. I have a .25 cal Impact X and I prefer it over the .35cal. The .25 is a laser beam up to 100m right out of the box. The .35 cal is all over the place at 100m, and unlike my .25 cal (older) impact x, does not maintain tight groups once the BAR drops below 65%. Slugs seem to work better than diablo pellets but overall the .25 cal is an all day hunting/varmint rifle while the .35 cal is a niche rifle. I believe the .30 cal impact mkii is the best overall FX rifle.

Labe from USA

Can the fx impact .35 cal be converted to compact version and vise versa?

asked Craig from USA

Yes, I have a .177 barrel, a .25 barrel, and a .35 barrel for my FX Impact M3. It's just a barrel and probe swap. Takes about 2 minutes to easily swap them out.

Donald from USA

How long will I wait for my FX impact x 35 after pre-ordering?

asked Matthew from USA

FX guns are shipped to AGD monthly. Back orders are shipped first, You may receive your order in one month . It may be longer.

Mark from USA

When switching it to a 30 cal what is the maximum energy do you get more power than the 30 cal gun

asked tyrone from USA

You will get approx 125-135 ftlbs

Mark from USA

What is the maximum pellet/ slug length that will feed through the magazine?
