FX 4 + Years with the same FX Impact M3

The FX IMPACT M3 first appealed to me for four reasons:

A. It was a bullpup. The breech is closer to the shoulder of the shooter reducing the arc at the muzzle for any movement at the shoulder. Allowing the rifle to be more accurate and the shooter more precise when shooting from a bipod.

B. The M3 trigger system is much, much smoother and crisper than the IWI Tavor X95 and absolutely awesome compared to the Tavor STAR-21.

C. It utilizes the Kalashnikov SV-99 straight-pull bolt design which doesn't move the rifle around anywhere near as much as a standard bolt allowing the shooter to remain on target to a much better degree.

4. I did not need to hand load rounds to achieve the proper internal/external ballistics for different projectiles. All my hand loading equipment was replaced by the rifle itself with the adjustable plenum regulator, Macro adjuster, Micro adjuster, and Air Valve.

BUT, out of the box, it was a COMPLETE JOKE for four reasons:

A. As a hunting rifle it had absolutely ZERO DURABILITY. Drop it one time striking the barrel system and your time in the field was over.

B. Mounting a bipod just in front of the trigger increased the arc at the muzzle to nearly the same arc at the breech decreasing the accuracy potential of the rifle when shot off a bipod.

C. No adjustable butt plate to establish the correct length of pull or the correct contact with the shoulder.

D. No adjustable cheek piece to establish the correct eye to scope or iron sights alignment.

HOWEVER, with aftermarket components from Kraford & Lypt and Saber Tactical, I upgraded my M3 to a pneumatic version of the Knight's Armament SR-25 E2 which made the M3 durable, functional, and, from a bipod, consistently accurate.

Now that my .177 M3 was durable, functional, and accurate, reliability became the question.

My M3 has been very reliable with all internal parts still original because:

A. Once the barrel system was installed and clocked, it has NEVER been removed. I clean the liner using a cable or by removing the butt plate and pellet pusher and using a cleaning rod. The rifle is cleaned after every use before leaving the range.

B. The 600 mm M3 is soft tuned for 9.57 grain domed diabolo pellets to less than 12 ft-lbs with the regulators at 120/70 bar, Macro at 1, Micro at 1.5 and Air Valve at the high side of 3 using a maximum tank pressure of 200 bar.

The rifle is a joy to shoot, I don't need sighters, I have had no POI shifts caused by the rifle and I haven't touched the elevation or windage settings on the MTC S.W.A.T Prismatic 10×30 scope for months and I shoot an average of 3 times a week outdoors from April through October and indoors from November through March.

Reminds me of my first Impact MK1 back when AOA was selling FX brand. It was a 600mm .25 with original S/T barrel. I shot it factory settings for over a year before changing pellet weights and settings, another couple year before I wanted to try something different and sold it without ever changing an Oring.
Daren told me before I purchased it that most problems were caused by user error. I also bought an M3 .22 standard. I have a .22 m3 wildcat and was considering swapping barrels on my impact but wanted to try something new. I traded it in for a leopard. I have only had the Leopard a couple days but i'm liking it.:)

What did you do about durability? I just posted a thread about the flimsy barrel and my on going progression to get it rigid.
I added a carbon fiber barrel sleeve, then a carbon fiber shroud sleeve, now I fashioned a clamp that finally solved the issue.

For the .117 I used a carbon fiber sleeve with just a touch of blue lock-tight at the breech end to fix it to the liner so I could clock the barrel system. I figured it was just like bedding one of my powder burners where every contact with the barrel was at the breech end allowing the barrel to freely thermally expand towards the muzzle uninhibited. I then protected the barrel system with a K&L top rail:

HOW EVER!!! Mr. Buck from CAPE FEAR AIRGUNS built this 600 mm 30 cal for me using a Saber Tactical long top rail. He carbon fiber sleeved the liner and clocked it for me, but notice the Saber Tactical top rail ends just before the barrel assembly and clamps snug to the barrel shroud leaving only the thread protector exposed:

Moderator on or off the POI stays within the 9 ring of a WRABF/ ERABSF 25 Meter target (~ 9/32" diameter) with no scope adjustments.

I am sending the 117 to Mr. Buck to replace the 600mm barrel system with a 500mm barrel system, convert the rifle to a true sub FAC < 12 ft-lbs rifle and shoot it unmoderated. The K&L top rail will then completely protect the shroud.
