This scope is great! I actually run this on my 6.5 Grendel AR15 and using the Impact Ballistics program I was able to hit targets out to 600 yards with no issue in less than 10 rounds out of the box. Read More

I know your info says this scope is built for the ar platform but will it work on a bolt gun also? This optic has what I’m looking for for my 308 build except I wanted 50mm, I’ll settle for the 42mm bc it has exposed turrets and is close to my price range

Answer

Yes, there is no reason why you could not use the RESPONSE on a bolt gun, in fact I personally use the RESPONSE 4-16X42 on a GA Precision Bolt gun in .308 often. Read More

Hi Jon, According to the ballistics calculator for my select round, 168 SMK, the Dope card shows 26.8 MOA at 800 and 40.4 MOA at 1000. The difference being 13.6 MOA. Would it be correct to dial to 13.6 and use the 800 yard mark on the reticle for targets at 1000. Thanks.

Answer

Hey Roman, It would not work that way. Once you dial the elevation adjustment, the position of the dots change in relation to the zero setting, so by adding 13.6 MOA, your 800 yard dot would not longer be 800 yards. The better way to… Read More

Hey Roman, It would not work that way. Once you dial the elevation adjustment, the position of the dots change in relation to the zero setting, so by adding 13.6 MOA, your 800 yard dot would not longer be 800 yards. The better way to do it would be to either dial the 40.4 MOA or dial the magnification down until one of the dots is close to a 1k impact.

Response 4x16x42. Assuming scope has to be zeroed at 100 yards and on 16 power for bdc to work correctly what happens to point of impact on 4 power when not wanting to shoot long range shot. Under 100 yard shots, some of my hunting shots have been really close. Thanks

The point of impact on the center crosshair does not vary with magnification as it is in the optical center of the riflescope. All other parts of the reticle change when the magnification is varied. One thing to note is that while the BDC reticle is designed to be used on the highest magnification the Impact Ballistic program on our website will show you the distances the dots represent at any magnification.

I've been looking for a quality scope to put on my M1A and your scope looks like a perfect fit but will it handle the recoil

Answer

Hello, yes, all TRACT scopes are built to withstand 1,000g of force, which is greater then virtually any modern centerfire rifle can produce. We have several customers who purchased the RESPONSE specifically for the M1A. Read More

Do you make custom reticles for 6.5 Grendel with a 123 grain bullet?

Answer

While we do not offer custom reticles, you can have a custom turret engraved and dial the distance, or you can use the Impact Ballistic program to match the cartridge to the reticle. Read More
