TFB Review: B&T SPR300 PRO


Designed in Switzerland with discretion in mind, the new B&T SPR300 PRO comes tailored for the U.S. market.  The new PRO model now accepts STANAG pattern magazines, comes chambered in 300 Blackout, and accepts AR-pattern accessories.  Thanks to B&T, I was able to spend a couple months reviewing this rifle to see just how good the new PRO model could be.

TFB Review – B&T SPR300 PRO – What’s in the Case

The review SPR300 Pro I was sent arrived in this hard case with bipod, cleaning kit, rifle, suppressor, magazine, a few additional adapters, and a user manual (not pictured).

TFB Review – B&T SPR300 PRO – Stock Locked Closed

For low-profile transport, the stock folds and locks to the left-hand side of the receiver.  To remove or install the bolt you simply push the bolt release button on the left rear side of the receiver.

TFB Review – B&T SPR300 PRO – Bolt Install

Installing the bolt quickly is very easy thanks to two polymer tracks at the back of the receiver.  These tracks help guide the bolt in quickly and quietly.  At the rear of the bolt, there’s a red indicator button indicating if the rifle is cocked and ready to fire.

Note:  The bolt cannot be installed unless it is in the cocked position.  If the bolt is de-cocked it has to be manually cocked using a 4mm drift punch prior to insertion.

TFB Review – B&T SPR300 PRO – Folding Stock Hinge

To lock and unlock the stock you press up on the pin at the rear right-hand side of the receiver.  The stock can also be swapped out using a supplied factory adapter for use with B&T’s BT-34058 folding stock, or AR-pattern stocks with a 1913 style adapter.

In addition, the grip on the SPR300 PRO can be swapped out with any AR pattern grip.  A Lancer 300 Blackout specific magazine was supplied with this review rifle, but any standard pattern AR mag will fit.

Oversized magazine release buttons are found on both sides of the receiver and are easy to use even with bulky winter gloves on.

TFB Review – B&T SPR300 PRO -Suppressor Assembly

The SPR300 PRO ships with a very sleek 18.25in sans suppressor weighing in at 1.15lbs.  Stock extended the rifle has an overall length of 39.27in and weighs 8.53lbs

TFB Review – B&T SPR300 PRO – Suppressor Removed

The sans suppressor slips over a 250mm (9.84in) 1:8 twist dual threaded barrel.  The cold hammer forged Hanel barrel and will accommodate the supplied sans suppressor or 5/8×24 threaded suppressors.

The suppressor tucks underneath the new NATO accessory rail (NAR).  This allows for the use of NVD or thermal clip-on devices to be mounted in front of the scope.  Additionally, a gas pressure relief valve has been added at the rear of the suppressor.  This design paired with an O-ring seal provides a very secure fitment of the supplied suppressor.

TFB Review – B&T SPR300 PRO – Fully Assembled

Last but not least is the new lightweight polymer bipod that’s supplied by B&T.  This uses a very simple QD style mount and weighs in at only 8 ounces.  This mounts at the front of the rifle where two QD sling swivel points can be found, alongside two at the rear.

With the rifle assembled and topped off with a VX5-HD 3-15×44, it was time to head to the range and see just how accurate this little swiss rifle was.

Accuracy Testing

TFB Review: B&T SPR300 PRO

TFB Review – B&T SPR300 PRO – Accuracy Testing

B&T advertises the SPR300 PRO as perfect for sniping missions out to 150 meters (165 yards).  So I snagged a 100yard underground lane at TNT Guns and Range to see how accurate the SPR300 PRO was using subsonic ammo.

Discreet Ballistics was kind enough to provide me with some of their 190gr subsonic ammo.  Alongside this, I used some 200gr S&B, and 205gr and 220gr ammo made by SIG.  As my initial groupings were not at all good, I decided to re-visit this testing with the help of fellow TFB writer Rusty S.  We found that having a bag under the rear of the stock was causing the rifle, and thus the groups, to shift.

Using a tripod this time instead of bags, I returned to the range with the remaining ammo, and here were the results.

TFB Review: B&T SPR300 PRO

TFB Review: B&T SPR300 PRO – Accuracy Testing Results

  • Discreet Ballistics 190grn Subsonic – 1.129MOA
  • Sellier & Bellot 200grn Subsonic – 1.332MOA
  • SIG 205grn Varmit/Predator Subsonic – 1.033 MOA
  • SIG Elite Match 220grn Subsonic – 0.92MOA

It became clear that the 1:8 twist barrel was going to prefer longer and heavier subsonic ammo.  With that in mind, I took the rifle farther up into the mountains to see how well it performed and sounded outdoors.

At the Range

B&T advertises the SPR300 PRO with “sound level produced is less than 191dB”.  Sound is always relative, and fortunately for me, I was able to shoot the SPR300 PRO in various conditions.  Particularly this day in heavy snowfall I gained a new appreciation for just how quiet the SPR300 Pro truly was.

Without a meter, myself (and everyone else that fired the rifle) could safely say that this is the quietest suppressed 300 Blackout I or they had ever fired.  The SPR’s reflex style suppressor has a massive internal volume that produces a very deep and low pitch sound.  Two gas relief ports at the front of the suppressor make the recoil a soft push and make it one of the few centerfire rifles I would describe as “Hollywood quiet”.

TFB Review – B&T SPR300 PRO – Pinch-to-Open Bipod

Sound isn’t the only strong point for the SPR300 PRO.  As delivered, it is true to form a deployment package.  Paired with an adjustable trigger with a 1-4lb pull, quick deployment bipod, and adjustable cheek riser the rifle really is ready to go out of the box.  No additional accessories are required (minus the optic and ammo of course).

Overall I couldn’t have been more impressed with the SPR300 PRO package.  By the end of the review, I found myself impressed with all the little details.  Like the supplied bipod that I often used as a rest on barricades or logs when moving and shooting.  Overall the rifle is a very discreet and sleek little package.

Pros and Con’s

My expectations for the SPR300 couldn’t have been higher going into this review, and the SPR300 PRO delivered.  Everything from the rifle itself to the supplied accessories have an amazing fit and finish.  I’d always chased the dream of shooting a “Hollywood Quiet” centerfire rifle, and this was finally it.

TFB Review – B&T SPR300 PRO – Pros and Con’s

While I loved the SPR300 PRO, it isn’t without a few shortcomings.  First and foremost is the barrel.  Yes, the 1:8 twist barrel will put sub-MOA groups on paper, but you’ll need to use heavier 220-225grn projectiles.  Additionally, the stock isn’t designed for your typical bench rest shooting where you would use a rear bag.  It does however work perfectly if you use your support hand to pull it against your shoulder.

The Verdict

TFB Review: B&T SPR300 PRO

TFB Review: B&T SPR300 PRO

A B&T SPR300 Pro isn’t cheap and comes with an MSRP of $5,170.  This alongside the fact that it’s a two-stamp rifle (SBR + Suppressor stamp) means this whole kit is going to set you back over $6k with any optic.  So trust me, I get it, it’s a tough sell.  A niche rifle that’s only rated for distances out to 150 meters with a price tag this high better be everything you’ve ever wanted and more.

I think it’s worth it.  Even at a price point this high, and wanting preferential treatment in terms of ammo it’s still worth it.  Why?  Because there’s simply no other competitor that’s as quiet, as discreet, and as complete as the SPR300 PRO as a package.

I did a little collaboration video on SPR300 PRO with the guys over at 1911 Syndicate that you can check out below.  Special thank you to Discreet Ballistics for sending over ammo for this review, and to TNT guns and Range for the use of their facilities.
