American Precision Arms is very excited to share the release of the Generation 3 Fat Bastard. It has been a long time coming but we wanted to make sure everything was perfect before offering something new.

The development of APA Gen 3 Fat Bastard was the result of American Precision Arms' constant pursuit of breaking the mold and a desire to meet the demands of the Long-Range and Hunting markets.  APA has combined the standards of high-level performance and reliability with distinctive design enhancements to improve both accuracy and performance. These enhancements benefit the shooter experience at the range and in the field where every advantage matters.

The roots of the new Generation 3 version of the Fat Bastard lie in the requests of the elite long-range precision rifle community. APA's goal was to meet the needs of those shooters while also maintaining their standards of pristine manufacturing. Among the design, changes are three key features. The advanced Unique Recoil Profile tunable top port design allows the shooter to fine-tune the muzzle movement for absolute target retention.  In addition to that, the new lock nut design creates a zero over rotating platform. Last, is the addition of a fifth Bastard port section that eliminates even more recoil than before.

NOT JUST STOPPING RECOIL, BUT LATERAL MOVEMENT AND MUZZLE RISE AS WELL, FOR A TRULY NEUTRAL SIGHT PICTURE.

URP (Unique Recoil Profile) Top Ports

This allows the shooter to not only combat direct recoil but muzzle rise and lateral movement based on the characteristics of their rifle, personal grip, stance, and the position they are shooting from.

We developed the U.R.P. Adjustable Gas System. These aren't just randomly placed top ports. Every port is placed adjacent to the internal Bastard tooth where there is maximum pressure build-up. This makes the adjustable ports directionally effective. 

The unique tunable gas system combined with the trademark APA ports work together to achieve a sight picture that moves less than ever before. There are 10 directional gas ports that can be tuned to counteract you’re U.R.P. (unique recoil profile).

 There are endless combinations to keep your sights on target. To calibrate the brake to your U.R.P., start testing with all the gas screws installed. Pay attention to the movement of your reticle, and begin removing the gas screws as the recoil requires.

 When the gas screws are removed on the right side, the rifle will be shifted left. For the opposite effect simply remove the screws on the left. The gas holes closer to the nut have a more dramatic effect and the ports closer to the brake crown have a lesser effect.  When you find your U.R.P. combination, Threadtite your screws into place.

Pilling
I loved these pants very much when I first purchased them the fit was amazing and the length was even better. Pants are very flattering. I wore them for the first time a few days ago only for a couple hours and pilling happened immediately! I am very annoyed at that fact because I purchased these pants at the end of March and I am not in my return window! I am Not a happy customer at all. Waste of money

Bought again but note the material was different .
Fit Type: 33" Inseam, Size: Medium, Color: White
Love these pants . Good quality. Good material and made well. Bought a second pair but they are lighter weight material which is nice for the summer. Will buy again. First heavier white material did not shrink. Not sure about the most recent material as I haven’t washed them yet. Size true to fit

Perfect linen pants
Absolutely love these pants. They are high quality material and well made. The legs aren’t too wide and the wide waistband with drawstring is very flattering. Perfect transition piece between seasons but are lightweight enough to wear during the heat of the summer. I liked them so well I bought in three other colors.

So flattering and comfy!
Fit Type: 31" Inseam, Size: Medium, Color: Deep Khaki
These are so cute and comfy, plus natural fiber. I got the brown and I’m coming back for the khaki. Love! *I’m 5’8” 136 lbs, got the 31 inch size Medium. They were super big until washing/drying- still big but I think Small would be too small. They are a very flattering fit, especially with the cute back pockets.

HIGH waist, correct sizing, ok fabric...NOT SEE THRU!! Cool pants though!
Fit Type: 31" Inseam, Size: Medium, Color: Deep Khaki
If it's a few inches ABOVE my belly button, inseam is correct... but then MED is SUPER baggy in the butt (I have a small butt maybe?) WELL MADE! NOT see thru!! Fabric is kind of stiff, BUT because it's a linen blend, may be beneficial for less wrinkles? 😃 Probably improve if washed. Also tried the small, belly/butt area is better, but super high and a little tight on me. NO off gassing 👏👏👏 Super versatile (dress up or down) Good price.
